Differences in chemical composition:
304 stainless steel: contains 18% chromium and 8% nickel, no molybdenum.
316 stainless steel: contains 18% chromium, 8% nickel and 2%-3% molybdenum.
Corrosion resistance comparison:
304 stainless steel: corrosion-resistant in general environments, but may corrode in highly corrosive environments.
316 stainless steel: has stronger corrosion resistance in salt water environments and chemical corrosive substances, especially suitable for chloride ion environments.
Application areas:
304 stainless steel: widely used in construction, kitchenware, furniture and food processing.
316 stainless steel: suitable for marine environments, chemical equipment and other occasions with high corrosion requirements.
Price and performance:
304 stainless steel: low cost, high cost performance, meet daily needs.
316 stainless steel: higher price, but better corrosion resistance and heat resistance, suitable for harsh environments.
All GNEE seamless steel pipes are PMI tested, eddy current tested, hydraulic tested, non-destructive tested, etc. We produce seamless steel pipes from high-quality round billets by hot rolling or cold rolling/cold drawing process.
Our welded steel pipes include ERW pipes, LSAW pipes, SSAW pipes. These pipes are produced in accordance with international standards such as ASTM A213, ASTM A312, ASTM A269, ASTM A789, ASME SB677, ASTM A790, etc.
