Machined material - Stainless-Steel

Hey! ! Teaching every Monday is coming again!

If you are not looking forward to trying to learn what new things do you want to learn this week?
That small chic said nonsense,
Let us cut into the theme!


Stainless steel is generally called a class of alloy steel containing 10% -30% chromium.

The following is a material that is precisely commonly used, which can be applied to different industries.


Sae Steel Grade


300 Series: Chromium-Nickel Stainless Steel

Model 301: Good ductility, used in forming products. It can also be hardened by mechanical processing. Good weldability. Anti-wear and fatigue strength is superior to 304 stainless steel, such as spring, steel constant, wheel cover.

Model 302: Corrosion resistance is 304, because the carbon is relatively high, and the strength is better.

Model 303: By adding a small amount of sulfur, phosphorus is more likely to cut by 304.

Model 304: Universal model; 18/8 stainless steel. Products such as: corrosion-resisting containers, cutlery, furniture, railing, medical equipment. The standard ingredient is 18% chromium plus 8% nickel. Bymomability, when the impurity content is high, it occasionally presents weak magnetic properties after processing, which can only be eliminated by heat treatment. It belongs to the stainless steel that cannot be changed by the heat treatment method.

Model 304 L: The same characteristics are equal to 304, but low-carbon is more resistant, fever treatment, but mechanical is poorly suitable for welding and non-ferrosive products.

Model 304 N: That is the same characteristic as 304, is a nitrogen-containing stainless steel, and nitrogen is in order to improve the strength of steel.

Model 316: After 304, the second is the most widely used steel species, mainly for food / industrial and surgical equipment, and adding molybdenum elements to obtain a particular structure of corrosion. Since it has better bleak corrosion capabilities than 304, it is also used as "marine steel". SS316 is usually used for nuclear fuel recovery devices. 18/10 stainless steel is usually in line with this application level. Specialized in chemical, seaside, etc., ship assembly, building materials.

Model 316 L: Low carbon is more resistant, fever treatment, products such as chemical processing equipment, nuclear generator, refrigerant reservoir.


400 Series: Fattite and Martensitic Stainless Steel

Model 416: Added sulfur improved the processing performance of the material.

Model 420: Higher carbon, hardness, higher strength, blade martensitic stainless steel, like Costley's Stainless Steel, British Golden Home Harry Brearley This earliest stainless steel, can do very bright, suitable Tool, spring, surgical appliance, razor cut, valve.

Model 430: Fatite iron stainless steel, decorative, magnetic, for example for car accessories. Good moldability, but temperature resistance and corrosion resistance are poor, suitable for buckle, cutlery, furniture. Its standardized component is 16 ~ 18% chromium, which is low in carbon. Such stainless steel has magnetic.

Model 440: High-strength cutting steel, a slightly high carbon, can achieve higher yield strength after proper heat treatment, hardness can reach 58 hrc, belonging to the hardest stainless steel. The most common application example is "Shaving Blade". There are three common models: 440a, 440b, 440c, and 440F (easy to work).


600 Series: Martensite precipitated hardening stainless steel.

Model 630: The most commonly used precipitated hardening stainless steel model, usually called 17-4; 17% Cr, 4% Ni.
