Heat-resistant steel is mainly used for long-term use in high temperature parts.
(1) Working temperature of heat-resistant steel castings.
Since 1952, China has been producing heat-resistant steel.

The processing and deformation of certain high alloy heat resistant steels is very difficult.特殊钢(如不锈钢、耐热钢、耐酸钢等)用于制造在特殊环境下工作的零件。
Special steels(such as stainless steel, heat-resistant steel, acid-resistant steels, etc.) are used to manufacture parts that work in special environments.
Heat-resistant steel and stainless steel nail-to-steel are cross-over in the range of use.化学工业和动力工业的开展,又促进了合金钢种类的扩展,于是不锈钢和耐热钢在这段期间面世了。
Chemical industry and power industry development, but also to promote the steel alloy breed expand,so stainless and heat-resisting steel during this period was born.特殊钢(如不锈钢、耐热钢、耐酸钢等)用于制造在特殊环境下工作的零件。
Special steel(such as stainless steel, heat-resistant steel, acid resistant steel, etc.) is used to manufacture parts working in special environment.奥氏体不锈钢的特点是相变温度很高,所以可以用作耐热钢。
Austenitic stainless steel is characterized by a high phase change temperature,so can be used as heat-resisting steel.C)高合金耐热钢:在此类钢中合金元素多,合金元素含量一般在10%以上,甚至高达30%以上。
High alloy heat resistant steel: in this kind of steel, the alloy element content is more than 10%, even more than 30%.耐热钢铸件与其接触的气体,状况(包括风速含尘量、含化学成分等)。
(3) Gases in contact with heat-resistant steel castings, conditions(including wind speed, dust content, chemical composition, etc.).化学工业和动力工业的发展,又促进了合金钢品种的扩大,于是不锈钢和耐热钢在这段期间问世了。
Chemical industry and power industry development, but also to promote the steel alloy breed expand,so stainless and heat-resisting steel during this period was born.
Heat resistant steel castings and stainless acid resistant steels cross each other within the scope of use.作为不锈钢耐热钢使用最广泛,食品用设备,一般化设备,原子能工业设备。
As the most widely used stainless steel heat-resistant steel, food equipment, general equipment, atomic energy industrial equipment.如前所述.耐热钢是指在高温下具有较高的强度和良好的化学稳定性的合金钢。
As mentioned above, heat resistant steel refers to alloy steel which has high strength and good chemical stability at high temperatures.这类钢的某些牌号还可作为耐热钢(包括奥氏体型、铁素体型、马氏体型和沉淀硬化型)使用;.
Some of this kind of steel can also be used as heat-resistant steel(including austenite, ferrite, martensitic, and precipitation hardening);世纪20年代以后,不锈钢和耐热钢在这段期间问世了。
After 1920s, stainless steel and heat resistant steel came out during this period.其化学成分应分别符合GB1220-92《不锈钢棒》和GB1221-92《耐热钢技术条件》.
Its chemical composition should meet GB1220-92"stainless steel rod" andGB1221-92"heat-resistant steel technical conditions".最主要的用途是合金铸造――尤其是与铬及其他金属铸成合金以生产不锈钢和耐热钢。
The biggest use is in alloying-particularly with chromium and other metals to produce stainless and heat-resisting steels.奥氏体不锈钢的特点是相变温度很高,所以可以用作耐热钢。
Austenitic stainless steels are characterized by high phase transition temperatures andcan therefore be used as heat resistant steels.可见,耐热钢的高温强度不仅与化学成分有关,而且还与组织有关。
The high-temperature strength of heat-resistant steel is not only related to chemical composition, but also to microstructure.
They can beused both as stainless steel acid-resistant steel and as heat-resistant steel.
Some stainless steels have the characteristics of heat resistant steel.
Heat resistant steel should be considered in the spring working under high temperature.随着在高温工作的石油化工、航空航天和动力机械的发展,耐热钢也获得了迅速的发展。
With the development of petrochemical,aerospace and power machinery working at high temperatures, heat-resistant steel has also developed rapidly.另外,尽管金属模具使用耐热合金钢,但是其耐热性仍然受到限制。
In addition, although the metal mold USES heat-resistant alloy steel, its heat resistance is still limited.公司为用户开发的100MW火电耐热钢锻件成功替代国外进口产品。
The heat-resisting steel forgings we developed for 100MW thermal power generating unit has successfully replaced imported products.所以对高温下使用的耐热钢的使用性能基本的要求有两条。
Therefore, there are two basic requirements for the performance of heat-resistant steel used at high temperatures.
