400 series stainless steel is a kind of iron, carbon chromium alloy. This stainless steel has a martensitic structure and an iron element, so it has normal magnetic properties. 400 series stainless steel has a strong resistance to high temperature oxidation, and compared with carbon steel, its physical properties and mechanical properties have been further improved. Most 400 series stainless steel can be heat treated.
Commonly used 400 series of stainless steel varieties containing chromium 18% 430 and chromium 13% of the 410 and 420 stainless steel models, 430 stainless steel models which use the largest. 430 stainless steel model is characterized by low price, thermal expansion coefficient is small, resistance to chloride stress corrosion is better than 300 series stainless steel varieties; but its shortcomings is that the forming performance, weldability and tensile strength of less than 300 series stainless steel, Therefore, its use area is limited. In the case of the same amount of chromium, such as in the atmosphere, fresh water and nitric acid oxidation medium, 400 series stainless steel varieties corrosion resistance and 300 series of stainless steel varieties, and usually 400 series stainless steel varieties corrosion resistance is better than 200 series of stainless steel varieties. The 400 series stainless steel varieties currently add trace niobium, titanium, copper and aluminum elements can improve its deep drawing performance, weldability, corrosion resistance and high temperature strength, can be partially replaced by 300 series stainless steel models.

Excellent Corrosion Resistance

One of the most important properties of 400 stainless steel is its excellent corrosion resistance. This alloy contains chromium, manganese, silicon, and carbon, which work together to provide superior resistance to a wide range of corrosive environments. Also, 400 stainless steel is resistant to intergranular corrosion, making it an ideal choice for high-temperature applications.

Good Formability and Weldability

400 stainless steel also has good formability and weldability. This alloy can be easily formed and welded using various methods, making it an ideal choice for many applications. Also, 400 stainless steel has good resistance to scaling and oxidation at high temperatures, making it a perfect choice for high-temperature environments.

Good Strength and Toughness

In addition to its excellent corrosion resistance, 400 stainless steel has good strength and toughness. This alloy contains a high percentage of chromium, which provides good strength and hardness. Additionally, 400 stainless steel has good impact resistance and can be heat treated to increase its strength and hardness.

Economical

Another advantage of 400 stainless steel is that it is an economical choice for many applications. This alloy is less expensive than other grades of stainless steel, making it an ideal choice for budget-conscious consumers. Additionally, 400 stainless steel is widely available and easily sourced from various suppliers.

Resisting corrosion well, 410 stainless steel is also known for its hardness and strength. It contains chromium at a percentage of at least 11.5 percent, just enough to make it useful as a corrosion-resistant alloy in certain environments, including those containing mild chemicals or steam. Often provided in machinable but hardened condition for applications requiring moderate resistance to corrosion and heat, along with high strength, this steel grade resists corrosion best when hardened, tempered and polished.

Applications include: Blades for gas and steam turbines、Bolts, nuts and screws、Components for pumps, including shafts and valves、Cutlery、Dental and surgical instruments、Hardened steel balls and seats for、Kitchen utensils、Mine ladder rugs、Nozzles、Oil well pump components like hardened steel balls and seats.
