410 (1Cr13) stainless steel round bar with high quality

New country signs: 12Cr13 (GB / T 20878-2007)

Standard: Stainless steel bar (GB / T 1220-2007)

Stainless steel cold-rolled steel sheet and strip (GB / T3280-2007)

410 is martensitic stainless steel, good hardenability it has a high hardness, toughness, good corrosion resistance, heat and cold deformation performance, shock absorption is also very good.


Require high temperature or low temperature tempering, but should be avoided between 370-560 ℃ tempering treatment.

Scope of application:
1Cr13 stainless steel round bar has good corrosion resistance, machinability, general blade, mechanical parts, tableware (spoon, fork, knife, etc.).

1Cr13 Chemical composition:
C: ≤ 0.15, Si: ≤ 1.00, Mn: ≤ 1.00, P: ≤ 0.04, S: ≤ 0.030, Ni: ≤ 0.60, Cr: 11.50 to 13.50

Mechanical properties:
Tensile strength σb (MPa): ≥540
Conditional yield strength σ0.2 (MPa): ≥345
Elongation rate δ5 (%): ≥25
Section shrinkage ψ (%): ≥55
Impact energy Akv (J): ≥78
Hardness: ≤200HB; ≥159HB

1Cr13 quenching heating temperature: 1000-1050 degrees, insulation 1 to 3 hours, air cooling, according to the tempering temperature of different levels, hardness varies.

Heat treatment specifications and microstructure:

Heat treatment specifications: 1) annealing, 800 ~ 900 ℃ slow cooling or about 750 ℃ ​​fast cooling; 2) quenching, 950 ~ 1000 ℃ oil cooling; 3) tempering, 700 ~ 750 ℃ ​​fast cooling.


Metallographic organization: organizational characteristics for the martensitic type.

Delivery status: generally heat treatment status delivery, the type of heat treatment specified in the contract; not marked, according to the state of non-heat delivery.

Uses: the production of weak corrosive media and bear the load parts, such as turbine blades, hydraulic valve, bolts, nuts, etc. are mainly used for the requirements of high toughness,

Such as cutting tools, blades, fasteners, hydraulic press valves, thermal cracking anti-sulfur corrosion equipment, etc.,
