What are the uses of 09CuPCrNi-A landscape used steel

The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

35# steel is a high-quality medium carbon carbon structural steel, with good plasticity and appropriate strength, good process performance, and acceptable welding performance. It 09CuPCrNi-A landscape used steel is often delivered in normalized and tempered state. 35 # steel is widely used in the manufacture of various forged and hot-pressed parts, cold-drawn and 09CuPCrNi-A landscape used steel upset forged steel, seamless steel tubes, and parts in machinery manufacturing.

The difference between 09CuPCrNi-A landscape used steel, 10# seamless steel pipe and 20# seamless steel pipe:
1. Chemical composition
Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25
2. Mechanical properties
10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
