Product Introduction

SS Pipe grades including ASTM A312 TP304L

304L is a variant of 304 stainless steel with a lower carbon content and is used in applications where welding is required. The lower carbon content minimizes the carbides precipitated in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding erosion) in stainless steel in some environments.
304N is a nitrogen-containing stainless steel, and nitrogen is added to improve the strength of the steel.
