  • Quenching & Tempering Clifton Steel

    After the metal is heated, we need to rapidly cool the steel. As material is quenched, the austenitic grain structure created during the heating stage transforms to different grain structures such as martensite, ferrite, pearlite, and cementite. The type of grain structure developed depends on how quickly the material is cooled.Read More

  • hardening mild steel Practical Machinist

    Oct 07, 2009 · A lot of hot rolled is A36 which simply has a minimum yield strength of 39,000 psi and ultimate of 58,000 psi. But these are minimums so there is nothing stopping a batch of A36 being way above this and having a carbon content much higher than mild steel. A36 is notorious for uneven composition even within a single length of bar.Read More

  • Quenching of SteelPurpose and Mechanism Industries

    Oil cools hot steel less rapidly than water, and the larger the piece quenched, the slower is the cooling rate. One advantage of the slower cooling is reduced danger of warping.

  • 7 Causes For Quench Cracking Of Steel Speaking of

    Here are 7 ways that steel can fail as a result of Quench Cracking from heat treatment. Overheating during the austenitizing portion of the heat treatment cycle can coarsen normally fine grained steels. coarse grained steels increase hardening depth and are more prone to quench cracking than fine grain steels. Avoid over heating and overly long dwell times while austenitizing.Read More

  • Understanding Case Hardening of Steel Design News
