Acewell Industry is one of the top manufacturers and suppliers in 444/446/431/440A/B/C stainless steel pipe/tube. We have more than 20 years of experiences in producing high quality stainless steel and alloy products. We provide the best prices, high quality, good service, and quick delivery time.

Product Details: SUS444 (00Cr18Mo2) is a ferritic stainless steel with ultra-low carbon nitrogen, 18% chromium and 2% molybdenum, and high corrosion resistance. 446 stainless steel has strong high temperature corrosion resistance, and does not produce easily peeled oxide scale below 1082 °C. 431 obtain high mechanical properties through heat treatment, and its corrosion resistance is better than 410 steel and 430 steel. 440A has the least amount of carbon making this the most stain-resistant. 440B is slightly more carbon than 440A. 440C has the greatest amount of carbon of the type 440 variants.

Applictaion: 446 used in the combustion chamber. 440A/440B/440C more desirable in knifemaking.

Inspection: Strict inspection is from raw materials to finished product. Eddy Current Testing before packaging is must. Unqualified products will be destroyed. Third party inspection is accepted.

Package: Wooven bags, plywood box, wooden box, plastic cap on both ends, or customized. Standard export sea-worthy packaging, inner waterproof paper with outer iron packaging which is fixed on a fumigated woodenpallet. It can effectively protect products from corrosion and various climate changes during ocean transportation.

Certificates: We have ISO, SGS, TUV, BV etc.

Shipping Service: We have self-operated logistics at cost price, and cooperate with overseas agents all over the world to make delivery safely, timely and easily.
