Product Description

Alloy Steel DIN 1.5919 3115 Hot Rolled Round Bar


1: DIN 1.5919 Steel Introduction

  15CrNi6/1.5919  is a low-alloy steel containing chromium and Nickel as strengthening elements.It has good mechanical property for highly strained parts and good toughness at core tensile strength of 900 - 1200 N/mm2. This material is generally used driving bevel gears, crown wheels, gears, shafts, bolts for automotive and gear components.

8: DIN 1.5919 Steel Heat Treatment

Normalizing For 15CrNi6

Nominal normalizing temperature:850-880°C

Hold the temperature for several hours

Cooling in the air
Annealing  For 15CrNi6

Nominal Annealing temperature:650-700°C

Cool slowly in the furance

Maximum Brinell hardness of 229
Hardening and Tempering(QT)  For 15CrNi6

Nominal Hardening temperature:820-870°C

Hold at this temperature then quench in oil or water

Tempering  as soon as possible when the temperature low to ambient

Heat uniformly to the suitable temperature.

keep the material out of the furnace ,then cool in the air
