Product Description

Alloy Structural Steel AISI ***0 is a chromium molybdenum alloy steel that is supplied in either the annealed or prehardened condition, it can be used as a holder material for high strength structural components.

> Weldability suffers with increasing chromium content.

> High temperature strength and high pressure hydrogenation perperties are promoted by chromium and molybdenum.

> Molybdenum significantly reduces temper brittleness.

Heat Treatment:

Forge: at ***0°C****0°C Cool slowly and anneal immediatedly

Anneal: at **0°C***0°C Cool slowly in furnace

Stress Relieve: at to **0°C***0°C Cool in still air

Harden: Preheat at **0°C***0°C raise to **0°C***0°C Cool in air, iol or into salt bath held at **0°C***0°C and then air cool

APPLICATIONS: Used for shafts, gears, cylinders and columns for industry mechanics in general.

Construction of mold, make large-medium plastic mold.

For compression molds where the etching is not required.
