304L Stainless steel
304L austenitic stainless steel is a low carbon version of 304 and is melted as AOD, AOD + VAR, or VIM + VAR melt type. This grade offers a good combination of strength, corrosion resistance, and fabricability. The low carbon helps improve weldability as compared to the 304 as well as improved corrosion resistance.
Introduction
The 304L chromium-Nickel austenitic stainless steel is easy to be processed by forging, rolling, hot perforation and extrusion. The ingot heating temperature is 1150 ~ 1260℃, and the deformation temperature range is 900 ~ 1150℃. This alloy is one of the most widely used stainless steels showing up in just about every industry.
