400 series ferritic and martensitic stainless steel.
1. Iron type stainless steel (ASTM grade) : 405, 430, 430F, 434, XM27;
2. Martensitic stainless steel (ASTM grade) : 403, 405, 410, 416, 420, 431, 440A, 440B, 440C,
PRODUCT INFORMATION
400 series stainless steel is an alloy of iron, carbon and chromium. Because it does not contain nickel, it is a nickel-free stainless steel, also known as stainless iron. 400 series stainless steel has normal magnetic properties because it contains martensitic structure and iron.

The 400 series mainly uses stainless steel types
Ferritic steel | 430 | It is a representative of ferritic steel, which has low thermal expansion rate, excellent formability and oxidation resistance. But the temperature resistance and corrosion resistance are poor. Suitable for heat resistant appliances, burners, household appliances, tableware, kitchen sink, decorative lights field. And its low price, good processability, is an ideal substitute for 304; Good stress and corrosion resistance, typical non-heat treatment hardening ferritic system stainless steel. |
409L(00Cr12Ti ) | Usually used as automobile exhaust pipe, ferritic stainless steel (chromium steel), excellent weldability, formability and corrosion resistance; Cr content 12%, high temperature and room temperature with BCC structure of ferritic stainless steel; The high temperature corrosion resistance and high temperature strength are better due to the addition of Ti element. Applied to automotive exhaust pipes, heat switches, containers and other products without heat treatment after welding. | |
Martensitic steel | 410(1Cr13) | Martensite represents steel (high strength chromium steel), with high strength, high hardness (magnetic), good wear resistance, good processability, after heat treatment can make the surface hardening and other characteristics;The disadvantage is poor corrosion resistance and is not suitable for use in severely corrosive environments |
420 | "Tool grade" martensitic steel, similar to Brinell high chromium steel this earliest stainless steel. Also used in surgical plants can do very bright. | |
440 | High strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can obtain high yield strength, hardness can reach 58HRC, is one of the hardest stainless steel. The most common example is razor blades. There are three common models :440A, 440B, 440C, and 440F(easy to process). | |
410L | On the basis of 410 steel, the c content is reduced, and its processability, resistance to welding deformation, high temperature oxidation resistance is excellent. Applied to mechanical construction parts, engine exhaust pipes, boiler combustion chambers, burners. | |
420J1 | High hardness after quenching, good corrosion resistance. Used in tableware (knives), turbine blades. | |
420J2 | Martensite represents steel, high strength, high hardness (magnetic), good wear resistance, and can be heat treated to improve mechanical properties. But its corrosion resistance is poor, poor formability. After quenching, the hardness of 420J1 steel is higher than that of 420J1 steel, and it is widely used in processing tools, pipe nozzle, valve, plate ruler, tableware. | |
436L | Good heat and abrasion resistance, containing niobium element, excellent processability and weldability. Used in washing machines, automobile exhaust pipes, electronic products, etc. |
