20MnV alloy structural steel Business claims

20MnV alloy structural steel is a kind of material, can replace 20Cr, 20CrNi steel.

Edit summary 20MnV alloy structural steel Xinhui Steel Union 20MnV alloy structural steel. C: 0.17 ~ 0.24 Silicon Si: 0.17 ~ 0.37 Manganese Mn: 1.30 ~ 1.60 S S: Allowable Residual Content 0.35 (%) Chemical composition of the product (% by mass): A01202 Standard: GB / T 3077-1988 P: Allowable residual content 0.35 Cr Cr: Allowable residual content 0.30 Nickel Ni: Allowable residual content 0.30 Copper Cu: Allowable residual content 0.30 Vanadium V: 0.07 ~ 0.12 Mechanical properties Sample blank size (mm) 15 Heat treatment: the first quenching heating temperature (): Coolant: water, oil The second quenching heating temperature (): - Tempering heating temperature (): Coolant: Strength b (MPa): 785 (80) Yield strength s (MPa): 590 (60) Elongation 5 (%): 10 Shrinkage (%): 40 Impact energy Akv (J): 55 impact toughness kv (J / cm2): 69 (7) Brinell hardness (HBS100 / 3000) (annealing or tempering state): 187 delivery status: to heat treatment (normalizing, annealing, or high back Fire) or non-heat-treated state of delivery, delivery status should be specified in the contract. 20MnV alloy steel Main Features] strength Xinhui Steel Union 20MnV steel, ductility, toughness and hardenability than 20Mn2 steel as well, steel in oil critical quenching diameter of 7 ~ 14mm, machinability is still good, seepage Carbon when the growth tendency of small grain, but the tempering tempering brittle. This steel for carburizing steel, carburizing can be directly quenched, does not require secondary quenching to improve the heart tissue, can replace 20Cr, 20CrNi steel. This steel also has a certain degree of heat strength, weldability and good. Application can be used in the temperature range of 450 ~ 475 for the production of boilers, high-pressure vessels, large high-pressure piping and other high-load welded structure. In addition, can also be used for cold drawing, cold stamping parts, such as piston pins, gears and so on. Xinhui steel grades commonly associated section steel, properties and uses 1.
