Stainless steel is a common material in stainless steel with a density of 7.93g/cm3. It is also called 18/8 stainless steel in the industry. It is resistant to high temperatures of 800 degrees and has

Stainless steel does not rust easily, but stainless steel can also rust. The fact that stainless steel is not easy to rust has a lot to do with the composition of stainless steel.

Stainless steel and regular steel are composed of different alloys, so their hardness is also different. Normally, stainless steel is harder than ordinary steel, and stainless steel has higher corrosi

Chloride ions exist widely, such as table salt/sweat stains/sea water/sea breeze/soil, etc. Stainless steel corrodes very quickly in the presence of chloride ions, even more than ordinary low carbon s

430 is a ferritic stainless steel with 16.00-18.00% chromium and essentially no nickel, while 304 is an austenitic grade with 18-20% chromium and 8-10.5% nickel. The austenitic grade resists corrosion

Type 420 is a martensitic stainless steel with 12-14% chromium and 0.15-0.40% carbon that can be hardened to about 50-55 HRC for cutlery, valve trim, pump shafts and precision parts. This article expl

Duplex 2205 is a standard workhorse duplex stainless steel, while 2507 is a high-performance "super duplex" grade. The primary differences are that 2507 contains higher levels of chromium, molybdenum,

Duplex stainless steel 2205 combines an austenitic-ferritic microstructure with roughly twice the yield strength of Alloy 316L, a PREN of 33 - 34 and good resistance to chloride pitting and stress cor

Under normal circumstances, the ferrite content in austenitic stainless steel is 50%-60%, while the ferrite content in duplex stainless steel is higher, up to more than 75%.

347 stainless steel is similar to 321 stainless steel in that it is often used as a stable replacement for Type 304. However, in the case of 347, the stabilizer is columbium.

347 stainless steel pipe is a grade of stainless steel produced in accordance with American ASTM standards. 347 stainless steel pipe is equivalent to my country's 0Cr18Ni11Nb stainless steel pipe.

Alloys 347 and 347H are high carbon niobium stabilized austenitic stainless steels with added niobium.
