ASTM 5140 / EN 41Cr4 1.7035 Alloy Steel Bar / Rod Forged 130-1600mm
INTRODUCTION
AISI 5140 / DIN W N-R 1.7035 alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 28-34 HRc.
AISI 5140 / DIN W N-R 1.7035 steel Annealing delivery hardenss less than 250HB. With a lower carbon content range, So AISI 5140 / DIN W N-R 1.7035 alloy steel have good weldability.

Heat treatment Related
- Annealing of 1.7035 Alloy structural steel
Slowly heated to 850 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The 1.7035 alloy steel will get MAX 250 HB (Brinell hardness).
- Hardening of 1.7035 Alloy structural steel
Heated slowly to 880-920°C, Then after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
