17-7PH round bar PMI testing

Cold-drawn stainless steel bars are cold-finished, which means they are further processed after hot rolling. The hot-rolled and cold-drawn process helps improve bar dimensional tolerances, straightness, surface appearance, and overall physical properties. These SS bars are the most accurate compared to hot rolled bars. They have a smooth surface finish.

The most common problem with stainless steel alloys is that they tend to undergo a process called oxidation. Oxidative corrosion can weaken the structural integrity of any project. Use appropriate materials in combination with a good finish delay, or in some cases prevent corrosion. One such example is the use of 310 stainless steel round bars, which have excellent corrosion resistance. As a heat-resistant alloy, this austenitic steel is considered a versatile multi-faceted grade. From food processing to furnaces, grade stainless steel 310 round bars are used in countless ways.

Steel bars are one of the core components of any manufacturing
industry or for that matter any industry that relies on machineries.
Thanks to its versatile applications, steel bars find itself in the
epicenter of most of engineering industries, be it automotive, textile,
fabrication, construction, cement, ship building, paper and pulp,
defence, heavy earth moving equipments or aerospace.
The overwhelming popularity of steel bars is owed to the fact that
it is possible to be produced in varying types, shapes, sizes, and
grades of bars to cater the exact technical requirements. Steel
bars generally have the shapes such as flat, round, hexagonal,
square and channel and on most of the occasions, it is the shape
of the bar that defines its application area

We have a large selection of stainless steel rods for sale, ranging in diameter from 3mm to 152mm. We supply stainless steel rods in standard lengths of about 3 meters, but we can also cut rods up to 5 meters for you. We offer stainless steel bars in grades 304 and 316. Grade 304 is a general purpose grade and is ideal for welding. Grade 316 has excellent corrosion resistance. Therefore, it is often used outdoors, or in particularly harsh environments such as marine environments.

Austenitic stainless steels shall be heat treated and subjected to corrosion tests. The round bar rolling process takes place as the stainless steel is placed into the analysed continuous shape mill, which is released in the first eight mill stands. Controlling the raw material (dimensions, surface, number of melts) before rolling, then heating in walking beam furnaces according to the technology of heating steel grades. When heated to the proper temperature, it is subjected to the descaling action created by the heating process. The next stage is the technical operation of single-stand rolling. After the hot rolling process, the product obtained is cooled to ambient temperature. melting times), and then heated in a walking beam furnace according to the steel grade heating process. When heated to the proper temperature, it is subjected to the descaling action created by the heating process.

The Stainless Steel 304 Round Bar, as the name suggests is made up of 304 grade stainless steel material. It has around 18% chromium and 8% nickel in its chemical composition. The round bar shows high resistance to corrosion and enhanced strength properties. The material is quite strong with around 515 Mpa min tensile strength and min yield strength of 205 MPa.

Like other austenitic grades, these grades have excellent toughness even down to low temperatures, although other grades are often used in this environment.
Grade 310sL (and a proprietary version of this grade), a version of the 310s with a maximum carbon content of 0.03%, is sometimes used in very specific corrosive environments, such as urea production.

The steel of UNS S31254 is a super austenitic stainless steel. They are high-end stainless steels designed for impact toughness against chloride crevice corrosion, stress corrosion cracking and pitting corrosion. These are austenites with high nickel and chromium content.

Grade 410 stainless steel is a general-purpose martensitic stainless steel containing 11.5% chromium with good corrosion resistance. However, through a series of processes such as quenching, tempering, and polishing, the corrosion resistance of grade 410 steel can be further enhanced. Quenching and tempering can harden grade 410 steel. They are typically used in applications involving mild corrosion, heat resistance and high strength.

The benefits of using stainless steel 304/304L round bars include low carbon content, which eliminates carbon precipitation during welding. Stainless steel 304L round bars have higher tensile yield strength and have low temperature properties that respond well to cold work hardening.

This stainless steel round bar is an age-hardening martensitic stainless steel that combines high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short, simple low temperature treatment. Unlike conventional martensitic stainless steels.

This stainless steel round bar is very weldable. Strength, corrosion resistance and simplified manufacturing can make it a cost-effective alternative to high strength carbon steel and other stainless steel grades.

Grade 316L is a low carbon version of grade 316 stainless steel with increased resistance to surface corrosion and can be used in the same temperature range. It is also more commonly used in applications that require large size components to be welded. Although the 316/316L is widely considered the default choice for applications requiring marine grade products, it has reduced performance in warm salt water.

ASTM is the American Society for Testing and Materials, and A479 is “Standard Specification for Stainless Steel Bars and Sections for Use in Boilers and Other Pressure Vessels.” This general supply specification defines composition and mechanical property requirements for various stainless steel bars, whether hot or cold worked, round, hexagonal or square, and hot rolled or extruded shapes such as angles, tees and channels . It also includes basic details on sampling and certification requirements, product marking and particle size requirements.

Stainless Steel 310 Round Bar is a robust austenitic stainless steel grade bar used in a variety of industries.

Some of the properties found in these stainless steel round bars are excellent general corrosion resistance, resistance to sensitization, ease of manufacture, good formability, high tensile strength, robust construction, corrosion resistant body, long service life, high temperature resistance, Good dimensional accuracy and surface smoothness finish. In our high-operations manufacturing, the development of high-grade round bars is done under the appropriate supervision of a team of dedicated experts.

Stainless steel round bars are available in three grades. 304 is the most common grade with easy weldability, good formability and corrosion resistance. Grade 316 offers excellent corrosion resistance, making it ideal for harsh environments such as salt water or heavy industrial areas. Like grade 304, it is also easy to weld, but more difficult to machine. Finally, grade 303 is easier to machine, drill and cut than other grades. However, it is not as suitable for welding as grades 304 and 316.

This specification covers stainless steel hot and cold worked bars, including round, square, and hexagonal, as well as hot rolled or extruded shapes such as angles, tees, and channels for boiler and pressure vessel construction.

The absolute roughness of hot rolled stainless steel round bars is higher than that of drawn bars. This is not a problem when rebar is only used for strength and corrosion resistance properties. But when the bar is used for aesthetic applications and outdoor fixtures, cold drawn stainless steel round bar is preferred because of its smooth surface and less absolute roughness. Bars can also vary in size. Typical range is 5mm to 450mm radius.
