ASTM A312 Stainless Steel Pipe Polishing TP317 3 Inch SCH 40
Trait
Good corrosion resistance: the main alloying elements of 317 stainless steel are chromium, nickel and molybdenum, which makes it have excellent corrosion resistance, especially suitable for strong acid, strong alkali and high temperature environment.
Excellent mechanical properties: 317 stainless steel has a high tensile strength and yield strength,elongation is also relatively high, but also has a high hardness and impact toughness, can still maintain stable performance in high temperature environment.
Easy to process and weld: 317 stainless steel can be processed and deformed by a variety of methods, such as cold working, hot working, deep drawing, etc.
High temperature strength: 317 stainless steel can still maintain high strength and stable performance in high temperature environment, which makes it widely used in high temperature field.
