注：优质碳素结构钢（GB/T699-1999）：
钢中除含有碳（C）元素和为脱氧而含有一定量硅（Si）（一般不追赶0.40%）、锰（Mn）（一般不追赶0.80%，较高可到1.20%）合金元素外，不含其他合金元素（剩余元素在外）。 此类钢有必要一起确保化学成分和力学性能。其硫（S）、磷（P）杂质元素含量一般控制在0.035%以下。若控制在 0.030%以下者叫优质钢，其商标后边应加“A”，例如20A；若P控制在0.025%以下、S控制在0.020%以下时，称特级优质钢，其商标后边应加“E”以示差异。关于由质料带进钢中的其他剩余合金元素，如铬（Cr）、镍（Ni）、铜（Cu）等的含量一般控制在Cr≤0.25%、Ni≤0.30%、Cu≤0.25%。有的商标锰（Mn）含量到达1.40%，称为锰钢。
1. Introduction of no.45 steel plate:
45# is the trademark of steel. It is a kind of high-quality carbon structural steel, corresponding to Japanese standard S45C, American standard 1045 and German standard C45.It is characterized by a higher strength and deformation resistance than ordinary A3 steel.It is widely used in mechanical manufacturing, the mechanical properties of this steel is very good, the price is relatively cheap.
2. No. 45 steel plate Performance specification:
Fulfill specification GB/T711 perhaps WTB
3. No. 45 steel plate delivery status: hot rolling;Are fire;Normalizing and tempering;
4. No. 45 refer to the corresponding steel number:
GB code steel no. 45;JIS code Steel S45C/S48C;DIN code Steel No. 1.0503;DIN specification steel No. C45;British BS Specification steel No. Ic45/080a47;French AFNOR code steel NO. CC45;NF Code - Steel No. C45;UNI specification steel No. C45;Belgian NBN code steel No. C45-1;Swedish SS code steel No. 1650;Spanish code steel No. F.114;AISI/SAE code Steel No. 1045;World Standardization Arrangement ISO specification Steel No. C45E4.C45 Compliance specification :EN 10083/2-1991
5. Chemical composition of no. 45 steel high-quality carbon structural steel:
C: 0.42 ~ 0.50
Si Si: 0.40 or less
Manganese Mn: 0.50 ~ 0.80
S: sulfur 0.045 or less
P P: 0.045 or less
Chromium Cr: 0.40 or less
Ni Ni: 0.40 or less
Mo Mo: 0.10 or less
Note: High quality carbon structural steel (GB/T699-1999) :
The steel contains no other alloying elements except carbon (C) element and deoxidized silicon (Si) (generally not exceeding 0.40%) and manganese (Mn) (generally not exceeding 0.80% and higher than 1.20%) alloying elements.This type of steel is necessary together to ensure chemical composition and mechanical properties.The contents of sulfur (S) and phosphorus (P) impurity elements are generally controlled below 0.035%.If the control below 0.030% is called high-grade high quality steel, its trademark should be followed by "A", such as 20A;If P is controlled below 0.025% and S is controlled below 0.020%, super quality steel shall be called as "E" after the trademark to show the difference.The content of other remaining alloying elements, such as chromium (Cr), nickel (Ni), copper (Cu), etc. brought into the steel from the material is generally controlled at Cr≤0.25%, Ni≤0.30%, Cu≤0.25%.Some trademark manganese (Mn) content reached 1.40%, known as manganese steel.
