Will 09CuPCrNi-B steel rust?

Our company is a large 09CUPCRNI-B steel steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special 09CUPCRNI-B steel steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

For 09CUPCRNI-B steel buyers, the impact of the rise and fall of 09CUPCRNI-B steel prices is great. Because of the large amount of 09CUPCRNI-B steel purchases and the large amount of funds involved, many 09CUPCRNI-B steel purchasers will carefully consider the price issue, and some 09CUPCRNI-B steel purchasers who are far away will also consider the freight issue. When the price of 09CUPCRNI-B steel overall drops, a large number of 09CUPCRNI-B steel buyers will hoard in large quantities. When 09CUPCRNI-B steel prices rise, we should predict and stock up appropriately.

The weldability of 09CUPCRNI-B steel is good. It means that under certain process and construction conditions, 09CUPCRNI-B steel can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

The microstructure of the quenched and tempered alloy steel, 09CUPCRNI-B steel after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. 09CUPCRNI-B steel, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC 09CUPCRNI-B steel steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system. Sincerely welcome new and old customers to visit our company, BBBN company will always be your reliable choice.
