Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon steel pipes, alloy structure pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes and bimetal co

Grade 347 stainless steel is a stable alloy because it contains columbium + tantalum components. 347 stainless steel is ideal for long service life at high temperatures (800-1500ºF) and is resistant t

347H is ASTM standard steel, belongs to austenitic stainless steel, due to chromium Cr, nickel Ni, niobium Nb, its intergranular corrosion resistance and polysulfuric acid intergranular stress corrosi

1Cr18Ni9Ti/321 stainless steel (UNSS321 stainless steel) is a very stable stainless steel. At the temperature of 800-1500°F (427-816°C), chromium carbide precipitation conditions can still maintain go

321 stainless steel: It is Ni-Cr-Ti austenitic stainless steel. 321 stainless steel is Ni-Cr-Ti austenitic stainless steel, its performance is very similar to 304, but due to the addition of titanium

430Ti stainless steel belongs to the ferritic stainless steel, which belongs to the 400 series stainless steel. High purity 430Ti (Nb) than ordinary 1Cr17 (430) stainless steel has better weldability

Below 600℃, the thermal conductivity of all kinds of stainless steel is basically in the range of 10~30W/ (m•℃), and the thermal conductivity has an increasing trend with the increase of temperature.

SUS430 and SUS304 are both stainless steel, but SUS430 contains higher nickel and SUS304 contains higher chromium.

400 series stainless steel is an alloy of iron, carbon and chromium. Because it does not contain nickel, it is a nickel-free stainless steel, also known as stainless iron.

409 stainless steel is a general purpose chromium, titanium stabilized ferritic stainless steel, its main application is automotive exhaust systems.

409L ferritic stainless steel is a kind of chromium steel without nickel, has good corrosion resistance, oxidation resistance, high stress corrosion resistance, magnetic and has advantages in technolo

2205 duplex stainless steel is composed of 22% chromium,3% molybdenum and 4.5% nickel nitrogen alloy (austenite-ferrite) duplex stainless steel (2205 duplex steel).
