1.2311 Apparatus Steel


1.2311 apparatus steel stockholders and suppliers, carrying to the accomplished of the India. Kohli Adamant are stockholders and suppliers of  round bar, collapsed bar, bowl and block.  As an admixture apparatus steel casting 1.2311 is frequently supplied in the accustomed and choleric action with a accumulation acerbity of about 300HB. This steel gives an accomplished able accomplishment and is one of the a lot of broadly accustomed blueprint for apparatus cut artificial moulds and zinc die casting dies. This casting gives accomplished chafe attrition but if best apparent acerbity is adapted for compression moulding artificial dies or agnate tools, the steel can be case accustomed or nitrided.

We acceptable consign enquiries for apparatus steel. Acquaintance our sales appointment and argue our shipping policy for added details.

Applications

This tool steel grade is ideally suited for the production of plastic moulds. Typical applications include die holders, zinc die casting dies, backers, bolsters and injection moulds. The versatility of 1.2311 tool steel with its high tensile characteristics enables uses for a variety of other applications such as shafts, rails and wear strips


Carbon 0.35-0.45% Chromium 1.80-2.10%
Manganese 1.30-1.60% Molybdenum 0.15-0.25%
Sulphur 0.03% max Silicon 0.20-0.40%
Phosphorous 0.03% max

Heat the steel slowly, allowing sufficient time for it to become heated through. Begin forging at 1050°C. Do not forge below 930°C reheating if necessary. After forging, cool very slowly.


Heat uniformly to 770-790°C.  Soak well, cool slowly in the furnace.


When dies are heavily machined, we recommend stress relieving just before finish machining in order to relieve machining strains. Heat to 460-500°C. Soak well and allow to cool in the air.


Heat uniformly to 820-840°C until heated through. Quench in oil.


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