PCrNi3Mo是一种中碳低合金钢，也是高强度合金钢，也叫炮钢。

PCrNi3Mo执行标准：GJB3783A-2015

本标准规范适用于制造中小口径速射武器身管零件用直径或边长不大于180mm的热轧，锻制合金结构钢棒和锻件。

PCrNi3Mo冶炼工艺：

电炉+炉外精炼或电弧炉+电渣重熔。

PCrNi3Mo特性及适用范围:

PCrNi3Mo作为中碳低合金钢，调质处理后σs>833MPa。大多用于制造各类炮身管、炮尾、闩体等要求高强韧性的重负荷零件。 PCrNi3Mo is a medium-carbon low-alloy steel, also known as high-strength alloy steel or gun steel. The execution standard for PCrNi3Mo is GJB3783A-2015, which applies to hot-rolled and forged alloy structural steel bars and forgings with a diameter or side length not exceeding 180mm used for manufacturing barrel parts of medium and small caliber rapid-fire weapon tubes. The smelting process of PCrNi3Mo includes electric furnace + ladle refining or electric arc furnace + electroslag remelting. As a medium-carbon low-alloy steel, after quenching and tempering treatment, PCrNi3Mo has a yield strength σs > 833MPa. It is mostly used to manufacture various cannon barrels, cannon breeches, bolt bodies, and other heavy-duty parts requiring high strength and toughness.

PCrNi3Mo化学成分:

碳C :0.32～0.42；

硅Si:0.17～0.37；

锰Mn:0.25～0.50；

硫S :允许残余含量≤0.015；

磷P :允许残余含量≤0.020；

铬Cr:0.80～1.20；

镍Ni:2.75～3.25；

铜Cu:允许残余含量≤0.020；

钼Mo:0.20～0.30。

PCrNi3Mo力学性能:

抗拉强度σb (MPa):≥1030；

屈服强度σs (MPa):≥885；

伸长率δ5 (%):≥12；

断面收缩率ψ(%):≥50。

热处理规范及金相组织:

热处理规范:淬火850℃,油冷;回火600℃,油或空冷。

PCrNi3Mo交货状态：

钢棒已退火或高温回火状态交货。
