密度7.8 g/cm3

珠光體鋼- 合金元素主要為鉻和鉬，總含量不超過5%，具有優(yōu)良的高溫強度，500～600℃加工性能，成本低。廣泛用于生產(chǎn)600℃以下的耐熱零件，如鍋爐鋼管、汽輪機葉輪、軋輥、緊固件、高壓容器、管道等。代表鋼種有16Mo、15CrMo、12Cr1MoV、12Cr2MoWVTiB、10Cr2Mo1、25Cr2Mo1V、20Cr3MoWV。

馬氏體鋼——鉻含量7～13%，具有優(yōu)良的高溫強度、抗氧化性和耐濕腐蝕性，但焊接性不好。4Cr9Si2、4Cr10Si2Mo用于制造內(nèi)燃機的排氣閥，也屬于馬氏體鋼、

鐵素體鋼- 含有較多的鉻、鋁、硅，形成單相鐵素體結構，具有優(yōu)越的抗氧化性，耐高溫氣態(tài)腐蝕能力。但其高溫強度較低，室溫脆性較大，焊接性不好。鋼種，如 1Cr13SiAl、1Cr25Si2。

Heat resistant steel

Density 7.8 g/cm3

Pearlitic steel alloy elements are mainly chromium and molybdenum, with the total content not exceeding 5%. It has excellent high temperature strength, 500-600 ℃ processability and low cost. It is widely used to produce heat-resistant parts below 600 ℃, such as boiler steel pipes, turbine impellers, rolls, fasteners, high pressure vessels, pipes, etc. Representative steel grades include 16Mo, 15CrMo, 12Cr1MoV, 12Cr2MoWVTiB, 10Cr2Mo1, 25Cr2Mo1V and 20Cr3MoWV.

Martensitic steel with chromium content of 7-13% has excellent high temperature strength, oxidation resistance and wet corrosion resistance, but poor weldability. 4Cr9Si2 and 4Cr10Si2Mo are used to manufacture exhaust valves for internal combustion engines, and also belong to martensitic steel

Ferritic steel - containing more chromium, aluminum and silicon, forming single-phase ferrite structure, with superior oxidation resistance and high temperature gas corrosion resistance. But its high temperature strength is low, room temperature brittleness is high, and its weldability is poor. Steel grades, such as 1Cr13SiAl and 1Cr25Si2.
