Stainless steel nut nut performance data

Carbon steel of density is slightly higher than ferrite and horse's size stainless steel, and is slightly lower than Austrian's size stainless steel; resistance rate by carbon steel, and iron pigment size, and horse's size and Austrian's size stainless steel sort increments; line expansion coefficient size of sort also similar, Austrian's size stainless steel highest and carbon steel minimum; carbon steel, and iron pigment size and horse's size stainless steel has magnetic, Austrian's size stainless steel no magnetic, but its cold processing hardening generated into's body phase variable Shi will will produced magnetic, available hot processing method to elimination this horse's body organization and recovery its no magnetic.
Stainless steel compared to carbon steel and have the following characteristics:
1) high rates of resistance, about 5 times the carbon steel.
2) linear expansion coefficient than carbon steel 40%, and with the increase of temperature, linear expansion coefficient values are increased accordingly.
3) low thermal conductivity about carbon steel 1/3.
