316L Stainless Steel Coil & Sheet – Marine & Chemical Corrosion Grade
Product Overview
316L stainless steel is a premium molybdenum-alloyed austenitic grade, offering significantly superior corrosion resistance compared with standard 304. The addition of 2–3% molybdenum greatly improves resistance to pitting, crevice corrosion and chloride attack, while the low carbon content ensures good post-weld corrosion resistance. This 2B finish coil & sheet grade is the premium choice for coastal, marine, chemical and pharmaceutical applications requiring extended service life in harsh environments.
Why Choose CNB 316L Stainless Steel?
We source 316L stainless steel from top-tier mills with strict control of molybdenum and nickel content to ensure consistent corrosion performance. Every batch undergoes full material testing and verification to guarantee authentic alloy composition and mechanical properties. With extensive stock of standard sizes and custom surface processing capability, we can meet the most demanding corrosion and fabrication requirements.
