41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).

铬钼钢，又名中温抗氢钢，是指加入Cr（<10%）， Mo等合金元素以显著提高高温强度极限和蠕变极限的钢种，同时具有良好的抗氢腐蚀和耐高温的性能，因此被广泛地运用于炼油、化工等含氢 装置 和高温设备中，是压力容器常用的钢种之一。 1.淬火性好，可进行深度淬火，而不是市面上防锯形锁的表面淬火. 2.对回火脆性倾向少. 3.高温加工性好，加工后美观. 4.熔接性好. 5.冲击的吸收性能好，锤子砸上去会有反弹感，无法进行暴力破坏. 1.加工性好. 2.冲击的吸收性能好. 3.焊接容 …

42CrMo steel is a Chinese alloy steel, and has high strength and toughness, good hardenability, and no obvious temper brittleness. After quenching and tempering treatment, it has high fatigue limit and resistance to multiple impacts, and good low temperature impact toughness.

2016年12月13日 · Chromoly steel has an exceptional strength-to-weight ratio, meaning it is significantly lighter than regular steel while still providing equal or greater strength. As a result, chromoly steel is often used in industries such as aerospace, automotive, and bicycle manufacturing, where weight reduction is required.

2024年11月15日 · 42CrMo alloy steel is renowned for its exceptional combination of strength, toughness, and wear resistance, making it a material of choice in various high-stress applications across multiple industries. This section explores the key sectors where 42CrMo is extensively utilized, highlighting specific components and the reasons for its selection.

AISI 4130 steel (UNS G41300), also known as 4130 Chromoly steel, is a chrome-molybdenum series low alloy steel with high strength, toughness and hardenability, usually used in quenched and tempered condition.

EN 10297-1: 2003 Seamless circular steel tubes for mechanical and general engineering purposes. Non-alloy and alloy steel tubes. Technical delivery conditions. Weldability: Bad weldability due to the high crack danger. Hardenability: Medium-good hardenability, suitable for hot purposes till a temperature of 500 C. It can be hardened in oil.

35CrMo steel is a Chinese alloy steel for engineering purpose, it has high durability and creep strength at high temperature, and low temperature impact toughness is good.

1.铬（CR）：铬的添加可以提高CRMO钢的耐腐蚀性和硬度。常见的CRMO钢牌号包括：20CrMo、30CrMo、40CrMo等。 2.钼（MO）：钼的添加可以增加CRMO钢的强度和韧性，提高其热膨胀系数，从而使其适用于高温环境下的应用。常见的CRMO钢牌号包括：12CrMo、15CrMo、42CrMo等。

Chromium-molybdenum (also called chrome molybdenum, chrome moly, or Cr-Mo) and chromium-vanadium (also called chrome vanadium or Cr-V) are names for two families of steel alloys used in hand tool manufacturing. Which one is better? When properly manufactured and heat treated, they are chemically almost identical and perform similarly.
