The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy A633 Gr E steel density products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of A633 Gr E steel density stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of A633 Gr E steel density and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.
After quenching and tempering, 40Cr alloy steel plate and A633 Gr E steel density sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A633 Gr E steel density is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
With the increase of temperature, the yield limit of A633 Gr E steel density will decrease monotonically, but the tensile strength of A633 Gr E steel density will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A633 Gr E steel density. Near the blue brittleness temperature, the A633 Gr E steel density strength increases and the plasticity decreases. The elongation and section shrinkage of A633 Gr E steel density increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
A633 Gr E steel density, Low alloy steel plate is a general designation, mainly refers to the steel plate with alloy content less than 3.5%. Alloy steel in the market is distinguished by the total amount of alloy elements, mainly including low alloy steel, medium alloy steel and high alloy steel. When the total alloy amount is less than 3.5%, it is called low alloy steel; if the total alloy amount is 5-10%, it is medium alloy steel; and when the total alloy amount is more than 10%, it is high alloy steel.
