What is the difference between TP304, TP304L, and TP304H?
TP304 – Standard austenitic stainless steel, ideal for general corrosion-resistant applications.
TP304L – Low carbon variant, designed for welded applications and reduced risk of intergranular corrosion.
TP304H – High carbon variant, suitable for high-temperature service, maintaining strength at elevated temperatures.
Plates are available in thicknesses from 1 mm to 300 mm, with various surface finishes including 2B, BA, No.4 brushed, and mirror polished.
