Product Introduction

ASTM A312 TP304L Stainless Steel is a low carbon variant of type 304 stainless steel. TP304L stainless steel has a maximum carbon content of 0.03% for better resistance to intergranular corrosion, and also contains a minimum of 18% chromium and 8% nickel. SS 304l pipe has excellent corrosion resistance, high temperature resistance, excellent strength and reliable durability, and also has good plasticity and weldability. S30403 material is suitable for pharmaceutical, chemical, oil and gas and other environmentally sensitive applications.
