What are different Types of stainless steel?
Since stainless steel is harder and tougher than iron (mild steel), the power of
the machine and the hardness of the blade are required for processing such as
cutting, shaping, and bending. In addition to the high material cost compared
to iron, the reason why stainless steel products are expensive is largely due to
the difficulty of this processing.
Below, here are typically stainless steel types.
1-1. SUS304
SUS304: This content may be expressed as 18-8 stainless steel. It has good
corrosion resistance and heat resistance and is most commonly used. In
addition, various shapes such as plates, pipes, angles, and round bars are made
and easily available. Corrosion occurs in environments with strong chlorine and
acid. Corrosion cracking may also occur where it is affected by the heat of
welding. As a guide, the heat resistant temperature is 500 to 600 ° C.
1-2. SUS316
SUS316: A steel grade based on SUS304 with an increased amount of Ni and 2
to 3% molybdenum added. The addition of Mo improves acid resistance and
heat resistance. It is used when A193 B8 Bolts is inferior in durability and
corrosion resistance in an environment where chemicals, seawater, etc. are
handled.
Austenitic steels such as SUS304 and SUS316 cannot be hardened (hardened
by heat treatment), so they cannot be used for applications that require
quenching. Stainless steel for quenching is a martensite steel grade. Stainless
steel flanges manufacturers in India provide you the high-quality stainless
steel.
1-3. SUS430
SUS430: Compared to SUS304, it is inferior in corrosion resistance, but because
it is inexpensive, it is often used in kitchen supplies and household goods.
There is almost no problem if the environment is such that it is used around
water, such as at home. It may be interesting to try out whether stainless steel
products in the home can be attached to magnets. The advantage is that the
coefficient of thermal expansion is small. carbon steel pipe fittings
manufacturers in India are the best manufactures of steel in overall India.
As a measure against stress corrosion cracking in the SUS304 system, stainless
steel roofs, water heaters, and the like are often made of steel (SUS444) made
by adding Mo to SUS430 to prevent rusting.
1-4. SUS440C / SUS420J2
SUS440C / SUS420J2: A 13% Cr steel grade that hardens by quenching (heat
treatment), so it is used for spring applications and knives (kitchen knives).
Most stainless steel scales (rulers), kitchen knives, knives, and ball bearings are
made of this material. The amount of carbon determines the degree of quench
hardening. Carbon steel flanges manufacturers in India is the best steel
manufactures in India.
1-5. SUS410 series
SUS410S series: Corrosion resistance and heat resistance compared to iron,
and because it is an inexpensive stainless steel grade, it is used for exhaust
system parts (mufflers, etc.) of automobiles. In order to prevent corrosion
caused by antifreeze agents and exhaust chemical substances, the exhaust
members of automobiles are becoming stainless steel.
