acero inox placa lamina bobina 316H y 304H
Alloy 316H (UNS S31609) is a high carbon modification of Alloy 316 developed for high temperature service. This alloy has higher strength at elevated temperatures and can be used in structural and pressure vessel applications above 932¡ãF (500¡ãC). The higher carbon content of 316H also provides higher tensile and yield strengths than 316/316L, and its austenitic structure provides excellent toughness at low temperatures.
The corrosion resistance of Alloy 316H is comparable to Alloy 316/316L and better than Alloy 304/304L in moderately corrosive environments. It is typically used in process streams containing chlorides or halides. The alloy is resistant to atmospheric corrosion and moderately oxidizing and reducing environments. It also resists corrosion in polluted marine conditions.
It is the steel of choice for use in marine environments because it resists pitting corrosion better than other grades of steel. Its negligible response to magnetic fields means it can be used in applications that require non-magnetic metals. In addition to molybdenum, 316 contains many other elements in varying concentrations. Like other grades of stainless steel, marine grade stainless steel is a relatively poor conductor of heat and electricity compared to metals and other conductive materials.
The increased carbon content provides greater tensile and yield strengths. The austenitic structure of the material also gives this grade excellent toughness, even at low temperatures.
This steel is ideal for use in the petrochemical, gas and chemical industries. Maanshan Iron & Steel supplies grade 316H steel to a variety of customers including manufacturers of pressure vessels, industrial boilers and heat exchangers.
