American standard

The SAE J2340-300 – s is the standard of a high-strength solution strengthening steel, it is combined with phosphorus containing carbon and manganese enhancer or silicon as a solution, to achieve the minimum strength requirements. Carbon can improve the formability and weldability, tents, maximum limit of 0.13%. The maximum limit of 0.100% of phosphorus. The[more]

American standard X steel, the high strength steel is often referred to as HSLA steel, and alloy carbide and nitride formation elements, usually niobium, titanium and vanadium or single or mixed together. These elements and carbon, silicon, manganese, phosphorus, and are used together in order to achieve the specified minimum yield strength. Carbon content are[more]

  American standard Y type steel, this kind of steel is similar to X steel, just in the required yield strength and tensile strength between the minimum rules for the distribution of 100 MPa. Here are a few beautiful mark Y the performance of the steel is introduced: Mechanical properties of the product:    [more]

  American standard R type high strength recovery annealing steel or stress annealing steel resistance, mainly through the existence of cold artifacts to realize the reinforcement. Referred to in the type and S type X alloy elements can be more in order to improve the formability and weldability, carbon content are limited to 0.13%. The[more]

American standard DL steel is composed of ferrite and martensite = ultra-high strength of dual phase steel.  American standard D type steel chemical composition contains: 0.060% phosphorus and sulfur elements, 0.015% and 0.200% 0.200% copper, niobium, 0.150% chromium element, 0.060% molybdenum elements   Here are a few American standard dual phase steel product performance:  Mechanical properties[more]

DH steel group composed of ferrite, martensite and retained austenite (can also contain a small amount of bainite), the residual austenite content is between 5 ~ 10%, is on the basis of the extension in DP steel with high strength and high performance, use a small amount of residual austenite, by phase transformation induced plasticity[more]

Product introduction M type is the car standard martensite steel, is a kind of ultra high strength steel plate, carbon content determines their level of intensity. The ductility of them are limited. M the chemical composition of steel, 0.020% phosphorus, sulfur, 0.015% and 0.200% 0.200% copper, niobium, 0.150% chromium element, 0.06% molybdenum elements. Product parameters[more]
