1. The technology conditions referenced JIS G 4051-1979 standard regulation, apply to is not more than 160 mm thick plate.

2. The size, shape, weight and allow deviation

The steel plate size and shape, weight and deviation should be allowed to meet the provisions of the GB709-88.

3. Technical requirements

3.1 the chemical composition of the steel plate (melting analysis) shall conform to the JIS G 4051-1979 standard regulation, see table 1.

Table 1

 

C	Si	Mn	Ni	Cr	P	S
0.40～0.46	0.17～0.35	0.60～0.90	≤0.25	≤0.01～0.20	≤ 0.030	≤ 0.030

1.2 DI = 32 to 40 (target DI = 37), DI value calculation method for:

DI = Y * C ×Y * Mn ×Y * Si ×Y * Cr ×Y * Ni ×Y * Mo x 25.4

Note: coefficient by users with Y of the alloy content and Y CRT to search.

3.3 delivery status: is fire

3.4 mechanical properties: provide steel plate sample tensile test performance.

3.5 magnitude 5.0 degree of grain size of the frequency

3.6 surface quality should be consistent with the provisions of GB711-88 standard.
