What are the top 5 34crmo4 alloy steel for quenching and tempering suppliers in Indonesia
With the development of China's 34crmo4 alloy steel for quenching and tempering market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of 34crmo4 alloy steel for quenching and tempering products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.
Cold rolled steel sheet has high strength, high hardness, high surface finish and is generally thin plate, which can be used for stamping. The production process of 34crmo4 alloy steel for quenching and tempering, hot-rolled and cold-rolled steel plates is different. Hot rolled steel plate is rolled at high temperature, while cold rolled steel plate is rolled at normal temperature. Generally speaking, cold-rolled steel plate has better strength and hot-rolled steel plate has better ductility.
The chromium plays an important role in 34crmo4 alloy steel for quenching and tempering, Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. 34crmo4 alloy steel for quenching and tempering, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
