1. Forgings Technical Specification
This type of forging part is Nangong's usual forging products. The forging can be produced as per drawing or your specified requirements. Of course, more details can be well discussed after email or call us. Here are the detail information for your reference:
Technical requirements for forgings SA-350 LF2 CL1 1. Smelting process is in electric arc furnace with vacuum degassing. 2. Forging is delivered at heat treated condition: normalization and tempering. Heat treatment diagram shall be enclosed to Certificate. 3. Chemical composition is in accordance with specification SA-350 with the following limitations: Carbon equivalent СЕ=С+Мn/6+(Сr+Мо+V)/5+(Ni+Сu)/15 <0,47% (the content of elements in %) 4. Samples for tensile testing and impact bending shall be taken from each heat and shall have the same degree of forging reduction and shall be subjected to the same heat treatment as forgings they represent Samples should be collected in location associated with ½ value of thickness and in direction transverse to the main direction of treatment. 5. Mechanical properties are tested on supplied samples with specifying the following in each certificate: -at a temperature plus 20°С, mechanical properties shall correspond to specification SA-350; - hardness is not more than 197НВ. 6. Charpy impact test at a temperature minus 30°С, value of impact energy on three samples shall be 27J at minimal individual meaning of 20J. 7. UT 100% as per SA-388, ASME Code sect.VIII div.2 р. 3.3.4. 8. Surface roughness V Ra25 (V). 9. Limit deviation for inside diameter of forging is +1mm, and for outer diameter is - 1mm, and for other dimensions is ±1mm. 10.Designation, material, heat number shall be marked. Certificate is in accordance with EN 10204 3.1. |
