Introduction

You can find more information on our web, so please take a look.

1. (Reference standard UNI EN ISO ) steel is one kind of hardened and tempered condition, it is equivalent to AISI P20 tool steel.

Smelting method : EAF+LF+VD+ESR

Main Characteristics : Steel with excellent hardening penetration up to 400mm. Generally supplied in hardened and tempered condition with excellent polishing and photoengraving properties. This steel is suitable for nitriding (around 800 HV), chrome and nickel plating.

Supply form of 1. steel

DIN 1. tool steel, we can supply the round bar, flat bar, plate, hexagonal and square block. Diameters can be sawn to your required lengths as one offs or multiple cut pieces. Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar and precision ground steel plate can be supplied, providing a quality precision finished bar to tight tolerances.

Applications of 1. steel

1. Tool steel is a German Die steel, the steel by &#;super clean&#; production process, pre hardened, showing the height of micro pure and excellent homogeneous structure, excellent polishing and light etching engraving. After heat treatment, processing and polishing performance is good, can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness even (to 400mm thick), good toughness, good mechanical processing performance. Gold microstructure is martensite and bainite structure.

Main be applied to in zinc, aluminum, magnesium and its alloy die-casting mould ; Hot-pressing mold, all kinds of hot forging die; Metal extrusion die, die set.
