D2 / 1.2379/ X155CrVMo12-1 Steel
X155CrVMo12-1 / D2 / 1.2379 steel suppliers delivering to the whole of the Middle East. Nifty Alloys LLC are suppliers of this high carbon high chromium steel in bar, plate, sheet and rectangular block which can be cut to your requirements. X155CrVMo12-1 / D2 offers good toughness with very high wear resistance. It hardens in air with minimum distortion and offers a measure of corrosion resistance when polished. Suitable for tools operating under conditions of severe wear and abrasion or as an alternative to oil hardening grades when long runs are needed.

Ground Flat Stock
Subject to size suitability and availability pieces can be produced as ground flat stock in approximately 3 to 4 weeks. Standard and non-standard sizes can be made.
Forging
Heat the steel slowly and uniformly to 700°C then more rapidly to 900-1040°C. After forging slow cool.
Annealing
X155CrVMo12-1 is supplied in the annealed and machineable condition. Re-annealing is only necessary if the steel has been forged or hardened. To anneal, heat slowly and uniformly to 900°C. Soak for up to three to four hours and then allow to cool in the furnace. Re-heat to 800-1040°C and again soak for three to four hours. Allow the steel to cool in the furnace.
Stress Relieving
If heavily machined, ground or otherwise subjected to cold work, the relief of internal strains it is advisable before hardening to minimise the possibility of distortion. Stress relieving should be carried out after rough machining. To stress relieve, heat the steel to 600-650°C. Soak well and cool in the furnace or in air.
Hardening
It is preferable to heat the tools in a controlled atmosphere. If this is not possible, pack hardening is recommended. A reducing atmosphere is desirable. Pre heat X155CrVMo12-1 steel up to 750-800°C. and allow enough time to soak at this temperature. The temperature should then be brought up to 1020-1040°C for air cooling, or 980°C for oil quenching. Soak thoroughly at temperature for thirty minutes per 25mm of ruling section, then cool or quench accordingly.
