Best Quality 409 Stainless Steel Coil

409 stainless steel is a ferrite-oriented stainless steel.It is commonly used in mechanical, construction and other special projects. Because of the presence of austenite grains, the mechanical properties of the ability are greatly improved,like for hardness and crisp etc. Also because of the addition of a lot of minor alloying elements, the strength of hardness has also greatly improved.

409 stainless steel has also another variant of 409L,the major difference is for the Carbon containing.In most cases,otherwise it is specified,we name 409 to be same with 409L,as in our Chinese market and inside our Jawaysteel warehouse,most coils and sheets of 409 stainless steel are with Carbon less than 0.03%,

1) Chemical composition for 409 stainless steel coil
Carbon (C): ≤ 0.03%
Silicon (Si): ≤ 1.0%
Manganese (Mn): ≤1.00%
Phosphorus (P): ≤ 0.040%
Sulfur (S): ≤ 0.020%
Nickel (Ni): ≤ 0.50% (may contain)
Chromium (Cr): 10.5 to 11.7%
Ti;6(C+N) to 0.5%.
NB:0.17% Max.

2) Physical properity for 409 stainless steel sheet / coil
Density: 7.75 g / cm & lt; 3 & gt;
Melting point: 1427 ° C
Expansion coefficient: mm / ℃ (at 20-100 ℃)
Young's modulus: kN / mm &
Rigid Modulus: kN / mm &
Applicable standards: n / a (UNS)

3) Surface for 409 409L stainless steel coils
2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment conditions.

4) Case & project for your reference.
For 409 stainless steel coils and strips,many orders are in form of sheet,coil,strip,band or other flat tempering and quenching condition.Due to it contains enough of Ti element,so this material is very resist with heat change,environment effect and further more due to with 0.03% less Carbon,which is easy to be bended or twisted,so most buyer buy it to use for auto-mobile exhaust piping making.And due to with less alloy materials,so its pricing is not high at all.Most customers buy them as stock or for some car building and pipes making.
