hardox 500 density considered mild steel?

With the development of China's HARDOX 500 density 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 HARDOX 500 density products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and HARDOX 500 density general weldments that do not need heat treatment.

Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. HARDOX 500 density, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of HARDOX 500 density etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in HARDOX 500 density etc. steel is strictly controlled.

The yield strength of HARDOX 500 density, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled HARDOX 500 density plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive HARDOX 500 density industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
