Stainless steel coil is an alloy steel with smooth surface, high weldability, corrosion resistance, polishability, heat
resistance, corrosion resistance and other characteristics. It is widely used in various industries and is an important material in modern industry.
Stainless steel is divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure state.
Austenitic Stainless Steel
stainless steel with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25% and C≈0.1%. Steel has high toughness and plasticity, but low strength.
Martensitic Stainless Steel
A steel whose mechanical properties can be adjusted by heat treatment. It has different strength and toughness at different tempering temperatures.
Duplex Stainless Steel
Austenitic and ferrite each account for about half of the structure. When the C content is low, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the characteristics of austenitic and ferritic stainless steel
Ferritic Stainless Steel
It contains 15% to 30% chromium and has a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance.
Q:Can you send samples?
A:Of course, we can send samples to all parts of the world, our samples are free, but customers need to bear the courier costs.
Q:What product information do I need to provide?
A:You need to provide the grade, width, thickness, coating and the number of tons you need to purchase.
Q:About product prices?
A:Prices vary from period to period due to cyclical changes in the price of raw materials. .
Q:What are the certifications for your products?
A:We have ISO 9001, SGS, EWC and other certifications.
Q:How long does your delivery time take?
A:In general, our delivery time is within 7-45 days, and may be delayed if the demand isextremely large or special circumstances occur.
Q:Does the product have quality inspection before loading?
A:Of course, all our products are strictly tested for quality before packaging, and unqualified products will be destroyed.
Q:How to pack the products?
A:The inner layer has a waterproof paper outer layer with iron packaging and is fixed with a fumigation wooden pallet. It caneffectively protect products from corrosion during ocean transportation.
