30HN2MFA材料是一种特殊的稀有钢级材料，具有很强的淬透性，适用于中型和大型产品，用于在低温和高温环境中生产航空工业、汽车、电力和国防工业中的重型机械、发动机、车辆和枪管。尺寸为80mm时获得了最佳性能。这种钢用于生产驱动轴、车轴、连杆、轴、转子、圆盘、行星齿轮部件、万向节轴和步枪枪管。
30HN2MFA级产品容易剥落，可焊性有限，对回火不敏感，其热处理是在油中冷却的情况下进行的。该级别的轧制和锻造材料不具有耐腐蚀性，其可焊性特别有限，需要对产品进行预热。钢通常在软化退火后交付。
30HN2MFA material is a special, rare steel grade with great hardenability for products with medium and large dimensions, used to produce particularly heavy machinery, engines, vehicles, and rifle barrels in the air industry, automotive, power and defense industries in environments of lowered and elevated temperatures. The best properties are obtained to a dimensions of 80mm.The steel is used for the production of drive shafts, axles, connecting rods, shafts, rotors, discs, planetary gear components, cardan shafts, and barrels of rifles. Products in the 30HN2MFA grade are prone to flaking and exhibit limited weldability, insensitivity to tempering and their heat treatment is carried out with cooling in the oil.Rolled and forged materials in this grade do not exhibit corrosion resistance and their weldability is particularly limited - it requires pre-heating of the product. Steel most commonly delivered after softening annealing.
