Stainless Steel Pipe Tube A312/ A312M TP317 S31700 Used in furnace material
Introduction to products:
Stainless steel is called high alloy steel. They contain about 4-30% chromium. According to their crystal structure, they are classified into martensitic, austenitic and ferritic steels. Grade 317 stainless steel is an improved version of 316 stainless steel. It has high strength and corrosion resistance.
316 stainless steel plate and 317 stainless steel plate are molybdenum containing stainless steel, of which 317 stainless steel molybdenum content is slightly better than 316 stainless steel. Due to the molybdenum in the steel, the overall performance of the steel is better than 310 and 304 stainless steel, under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses.
APPLICATIONS :
Grade 317 stainless steel is used in the following applications:
