Product Description

A312/A312M TP317 S31700 Stainless Steel Pipe Tube In Pulping Paper And Textile

Product Overview

Stainless Steel Pipe Tube A312/A312M TP317 S31700 Used in furnace material

Stainless steel is classified as high alloy steel, containing approximately 4-30% chromium. Based on crystal structure, it is categorized into martensitic, austenitic, and ferritic steels. Grade 317 stainless steel represents an enhanced version of 316 stainless steel, offering superior strength and corrosion resistance.

Both 316 and 317 stainless steel plates contain molybdenum, with 317 having a slightly higher molybdenum content than 316. The presence of molybdenum enhances the overall performance compared to 310 and 304 stainless steels. In high-temperature conditions with sulfuric acid concentrations below 15% or above 85%, 316 stainless steel demonstrates extensive applicability.

Applications
