DIN17165 17 Mn 4 steel Chemical Composition,DIN17165 17 Mn 4 steel supplier
DIN17165 17 Mn 4 steel is a kind of material for boiler and pressure vessel steel. DIN17165 17 Mn 4 steel is mainly used to for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
There are five main elements in DIN17165 17 Mn 4 steel, carbon(C), manganese(Mn), phosphorus(P), sulfur(S) and silicon(Si).
DIN17165 17 Mn 4 steel Chemical Composition specific data is as follows:
C % 0.08-0.2
Mn % 0.90-1.50
P % 0.025
S % 0.015
Si % 0.40
Generally, if the carbon content in steel increases, the yield point and tensile strength will increase, however, the plasticity and impact resistance will decrease. If the carbon content is over 0.23%, the steel welding performance will deteriorate, so low alloy structural steel, which is used for welding, carbon content is usually less than 0.20%. High carbon content would reduce the steel atmospheric corrosion resistance ability, in the open yard high carbon steel is corroded easily. In addition, carbon can increase the steel cold brittleness and aging sensitivity.
Through the above data, DIN17165 17 Mn 4 steel contains 0.08-0.2% Carbon, we can know that, DIN17165 17 Mn 4 steel yield strength can reach 295 Mpa and DIN17165 17 Mn 4 steel tensile strength can reach 580 Mpa, however, the plasticity and impact resistance will decrease.
