Product Overview

Description

 

GB T8Cr/75Cr1/DIN 1.2003 Tool Steel

 

 

GB T8Cr/75Cr1/DIN 1.2003 tool steel stockholders and suppliers, delivering to the whole of World. Huangshi Youli Steel/Huangshi Smooth Industry and Trade are stockholders and suppliers of round bar, flat bar, plate and block. As an alloy tool steel grade GB 75Cr1/DIN 1.2003 is commonly supplied in the hardened and tempered condition with a supply hardness of approximately 200HB. This steel grade gives an excellent polished finish and is one of the most widely accepted specifications for mandrels,punches,crushing tools,razors. This grade gives excellent wear resistance and better hardening. This steel is also suitable for small tools due to a Rockwell hardness of 47-51 HRC.

Forging

 

Heat the steel slowly, allowing sufficient time for it to become heated through. Begin forging at 800-1000°C. Annealing at 700-720°C reheating if necessary. After forging, hardness is below 200HB.

 

Annealing

 

Heat uniformly to 700-720°C. Soak well, cool slowly in the furnace.

 

Stress Relieving

 

When dies are heavily machined, we recommend stress relieving just before finish machining in order to relieve machining strains. Heat to 180-200°C. Soak well and allow to cool in the air.

 

 

Hardening

 

Heat uniformly to 700-720°C until heated through. Quench in water.

 

Tempering

 

Heat uniformly and soak at the tempering temperature for at least one hour per 25mm of section. Allow to cool in still air.

Carbursing / Case Hardening

 

In order to obtain maximum surface hardness, moulds machined from GB T8Cr/75Cr1/DIN 1.2003 tool steel may be case hardened, which can achieve a surface hardness of 43 to 66 HRc.

 

 

 

 

Heat Treatment

 

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of GB T8Cr/75Cr1/DIN 1.2003 tool steel.

 

 

Quality Assured Supply

 

GB T8Cr/75Cr1/DIN 1.2003 carbon steel is supplied in accordance with our ISO 9001 : 2008 registration.
