Alloy Steel Bar - Atlas Steels

Nitriding steels can have higher surface hardness developed by absorption of nitrogen, when exposed to a nitriding atmosphere at temperatures in the range of 510-530C, after hardening and tempering. High tensile steels suitable for nitriding are:4130, 4140, X4150, 4340 Alloy Steel Fasteners - Boltport FastenersAlloy steel grades 4130, 4140, 4340 and 8620 (20MnCr5) are commonly used material for producing these high strength alloy steel fasteners. Alloy steel fasteners are supplied in quenched and tempered condition with charpy impact testing and are primarily used for low temperature bolting applications.

Controlling Hydrogen Embrittlement in Ultra-High

Hence, considerable-diffusible H may remain in a baked steel, even after heating for 100 h.'3 The 1-5 wppm level of residual-dissolved H, typical of Cd plating and subsequent baking, embrittles high strength AISI 4340 steel.22 Similar problems were reported for Cd-plated steel fasteners.23 Engineering Steel Grades Explained Edcon SteelIn addition to the standard peeled (< 100mm dia) and black bars (> 100mm dia), Edcon Steel stocks a comprehensive range of metric and imperial centreless ground 4140 bars. 4340 alloy steel is a heat treatable and low alloy steel, containing chromium, nickel and molybdenum. It has high toughness and strength in the heat treated condition.

Evaluation of toughness in AISI 4340 alloy steel

(untempered) AISI 4340 steel has shown that compared to conventional austenitizing at 870~ increasing the austenitizing temperature to 1200~ can raise the plane strain fracture toughness (Kic) by a factor of two (without reduction in yield strength). However, concurrent with this improvement in Kic there is an High Strength Steel Plate and Ultimate Tensile Sheet Grade:4340 high tensile steel Equivalent Grade; AS1444-1996 4340, BS970-1955, EN24, BS970 Part 3-1991 817M40, ASTM A29/29M 1991 4340, SAE/AISI 4340; Grade:EN25 high tensile steel Equivalent Grade; AS1444-1996 X9931, BS970-1955 EN25, BS970 Part 3-1991 826M31; Grade; EN26 high tensile steel
