customized 2507 1.4410 Zeron 100 hex nut

Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities to austenitic and duplex stainless steels in virtually all corrosive media, and critical pitting temperature Above 50¡ãC .

It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.

Known for its high impact strength, UNS S32760 exhibits no ductile-brittle transition, but only a slight decrease in impact energy with decreasing temperature.

There are different types of flanges such as slip on flanges, socket weld flanges, forged flanges, blind flanges, reducing flanges and many by their functions.

Due to the ferritic portion of the duplex structure of the alloy it is very resistant to stress corrosion cracking in warm chloride containing environments.

Alloy 2205 Pipe has a melting point of 1350 degrees C. These pipes have a wall thickness between 0.3mm to 50mm.

2507 Duplex Plate also exhibit better ductility and toughness compared to ferritic stainless steels, but they do not provide these properties as successfully as austenitic stainless steels.

These super duplex UNS S32760 round bars are available in a variety of shapes, sizes and diameters depending on the needs and requirements of the application and customer supplied specifications. These super duplex UNS S32760 round bars are resistant to localized corrosion.

The yield strength of this material is almost two times that of the usually used austenitic stainless steel grade.

2205 flange has good general corrosion resistance, high resistance to chloride stress corrosion cracking, as well as pitting and crevice corrosion.

The duplex steels are one type of stainless steels that have ferritic and austenitic phases in their metallurgic microstructure.

Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments

Super Duplex Steel UNS S32760 are dual phase austenitic-ferritic duplex fasteners manufactured from alloy containing chromium, nickel and molybdenum with restricted carbon content and minimum PREN42. Zeron washers have high strength, resistance to pitting, stress corrosion cracking, erosion and corrosion fatigue, crevice corrosion resistance.

Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved. Alloy 2507 has excellent localized pitting resistance.

Our duplex steel UNS S31803 fasteners are available in different grades such as industrial washers, industrial screws, stainless steel washers, stainless steel screws and more.

Duplex Stainless Steel UNS S31803 Hex Head Bolts Hex head and threaded bodies are available.

Super Duplex UNS S32750 is the most common Super Duplex grade on the market. UNS S32750 is a duplex stainless steel designed for use in corrosive chlorine-containing environments. It has very good localized corrosion and stress corrosion cracking resistance and high mechanical strength. Widely used in oil and gas, hydropower, pressure vessels, pulp and paper, structural parts and chemical tankers.

These grades are excellent for fixed service simple flange connections, but slightly less so when forming a complex metallic shape. Fortunately, the workability of duplex into complex and rounded structures is less of an issue in structural steel given the wide preference for simple mild steel in non corrosive applications.

It has the nominal composition of 22Cr-5Ni-3Mo-N with P number 10H.

The origin of Duplex steels can be traced back to the 1920s, with the first cast being made in Sweden in 1930. However, the popularity of using duplex only started to rise around 30 years ago when steelmaking technology became more advanced. The two types of metals used to make Duplex ¨C austenitic and ferritic ¨C are both fit for purpose in many types of scenarios but they both have weaknesses that prevent them from being used more widely.

Duplex stainless steels are approximately 50% ferrite and 50% austenite for optimum strength and corrosion resistance.

Stainless steel round bar is a cylindrical stainless steel product, which is widely used in auto parts, aviation, aerospace hardware tools, chemical industry and other industries. Stainless steel WNR 1.4301 wire is known for its amazing tensile strength and fabric power and is available in a variety of sizes according to customer requirements. They are the product of the best materials and primary strategies that conform to the established norms of the industry. In our assortment we have round rods with special type of ends to ensure short and tight fittings in pipes.

The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.

Zeron 100 Threaded Rod are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.SA 182 F55 is a forging grade of Alloy 32760 or UNS 32760 which is highly resistant to crevice corrosion and pitting alloy for variety of corrsives. It is 22% chromium duplex stainless steel.

ASTM A240 is a normative standard covering several chromium-based stainless steel grades manufactured in sheet, sheet, or ASTM A240 Gr 2205 strip.

Additionally, Duplex 2205 is the most widely used duplex grade on the market. Duplex 2205 alloy is a nitrogen-enhanced duplex stainless steel alloy. The effect of nitrogen is to significantly increase the corrosion resistance of the alloy; especially in the as-welded condition.

Supler Duplex Steel UNS S32760 stud bolt has a higher yield strength and lower ductility than the austenitic steels so fabricators may find that higher forming forces, increased radius of bending, and increased allowance for spring-back are necessary.

The presence of ferrite in the duplex 2205 welded pipe is what provides for an enhanced performance of this stainless steel grade in caustic media containing environments.
