Brand comparison: national standard (1C17MO6Ni5N) American standard (SISI201) Japanese standard (SUS201) German standard (1.4372)
Application areas:
201 stainless steel balls are widely used in various hardware industries, handicrafts, plastic products, such as lamps, switches, motorcycle parts, luggage, bearings, die-casting parts.

characteristic:
It belongs to the section of nickel-plated steel, austenitic steel, non-magnetic, with low price and excellent performance. It can be processed, welded and drilled with hardness HRC≤28. (Note: The new steel ball reminds you that 201 stainless steel ball can not be used in industries with high anti-rust and anti-corrosion requirements such as seawater or acidic substances).

Application areas:
304 stainless steel ball is widely used in the market for a wide range of steel balls, can be used in medical equipment, chemical, aviation, aerospace, plastic hardware: perfume bottles, sprayers, valves, nail polish, motors, switches, electric irons, washing machines, refrigerators , air conditioners, medicines, auto parts, bearings, instruments, bottles.
characteristic:
A typical representative of austenitic steel, generally non-magnetic, but will be magnetic after the ball, can demagnetize, HRC ≤ 26. Has good rust and corrosion resistance.
Comparison:
304HC stainless steel ball is softer and easier to prosess than 304 stainless steel ball. 304L stainless steel ball has stronger anti-rust and anti-corrosion performance than the above two. It is easy to weld and has excellent polishing performance. It is more suitable for industries with high surface requirements.

Application areas:
   316 stainless steel ball is a relatively high demand product, usually used in special industries such as medical equipment, chemical, aviation, aerospace: perfume bottles, sprayers, valves, nail polish, body accessories, mobile phone boards.
Characteristic:
   Austenitic steel, HRC ≤ 26, is more suitable for industries with higher anti-corrosion requirements, and all performances are better than 304 stainless steel balls.
Comparison:
   The 316L stainless steel ball is softer and tougher than white, so it is usually used for body accessories.

Application areas:
420 stainless steel balls are commonly used in industries where high precision and rust resistance are required: motorcycle parts, pulleys, stainless steel bearings, plastic bearings, crafts, valves, and petroleum.

Material comparison:
The domestic 420 is mainly divided into two types of steel balls, 2Cr13 steel balls (corresponding to the Japanese standard: SUS420J1 stainless steel ball), and 3Cr13 steel balls (corresponding to the Japanese standard SUS420J2 stainless steel ball). These two steel balls have hardness, and many customers have a misunderstanding. It is believed that the 410 stainless steel ball (corresponding to the national standard: 1Cr13 steel ball) and the 430 stainless steel ball (1Cr17 steel ball) also have the same hardness. Although the two steel balls are the same as the 4 series stainless steel ball, the metallographic structure is different: one is the martensitic steel. The other is a ferritic steel.

Characteristic:
The representative of martensitic steel, commonly known as stainless iron, is magnetic, has good rust resistance, and has a high hardness of HRC50-55.
