Alloy Metal Round Bar 1.7225/SAE4140 For EPTTry Q T

Solution Introduction
AISI 4140 Steel Bar, Metal Plate, Flats Supplier, Stockist and Exporter. AISI SAE 4140 alloy metal is a chromium molybdenum alloy steel specification commonly used in EPTT function large tensile steel for parts, like axles, shafts, bolts, EPTs and other applications. Similar to alloy quality AISI 4130 chrome moly alloy steel but with a marginally increased carbon content. The greater carbon material of AISI 4140 metal offers greater toughness and heat treatment abilities in comparison to AISI / ASTM 4130 alloy steels, even so it does have inferior weldability traits.

EPT
Preheat the steel cautiously, warmth to 1150 oC – 1200 oC maXiHu (West EPT) Dis.mum, hold right up until temperature is uniform during the EPT.
Do not forge underneath 850 oC.Following forging procedure the operate piece need to be cooled as gradually as feasible.

Heat Treatment

• Annealing
  Warmth ASTM 4140 steels to 800 oC – 850 oC, keep until temperature is uniform all through the EPT and awesome in furnace.
• Normalizing
  Warmth steel alloy 4140 to 870 oC – 900 oC, maintain right up until temperature is uniform throughout the EPT, soak for 10 – fifteen minutes and amazing in still air.
• Tempering
  Re-heat 4140 grade metal to 550 oC – seven-hundred oC as necessary, keep until finally temperature is uniform all through the EPT, soak for one hour per twenty five mm of EPT, and amazing in nonetheless air.

Hardening

AISI alloy 4140 metal bar, plate and square can be hardened by cold doing work, or heating and quenching.
SAE 4140 alloy metal is typically supplied prepared warmth treated to hardness in 18-22 EPTC. If additional warmth treatment method is necessary, then heat to 840 oC – 875 oC, maintain till temperature is uniform all through the EPT, soak for 10 – 15 minutes for every twenty five mm EPT, and quench in oil, h2o, or polymer as required.
