What‘s The Feature Of Gnee High Strength Low Alloy Steel?
Selection of raw materials: Gnee adopts new low alloy high-strength steel with low carbon and low sulfur as the main characteristics, and in terms of raw materials, strict requirements for high quality and high safety.
Manufacturing process: Gnee usually adopts traditional metal heat treatment methods such as high-temperature tempering, normalizing, and tempering, ladle argon blowing-continuous casting slab-hot continuous rolling, or electric furnace-ladle powder spraying-thick plate rolling mill process to produce low alloy high-strength steel. The steel is generally used after hot rolling in order to obtain uniform organization and stable properties.
Testing and Certification: Gnee conducts comprehensive testing of its products, including plasticity, toughness, weldability, hot and cold workability, and formability, as well as other tests and analyses to ensure compliance with international and national standards.
Documentation and Traceability: Gnee maintains detailed records and rigorous inspections of each batch of steel produced. Such as conformity standards for raw materials, quality certification systems, and the need to refer to international standards.
Continuous Improvement: Gnee is committed to the continuous improvement of its steel production technology and actively complies with the standards, specifications, and quality certification system requirements during the production process to ensure the quality of its products and the satisfaction of its customers.
Tensile strength: good experimental results in terms of toughness and strength, higher yield point or yield strength than ordinary carbon structural steel.
Brittle fracture resistance: with the development of steel structure from riveted to welded, in order to improve the brittle fracture resistance of steel, gradually to reduce the carbon content of steel and composite alloying direction change
Corrosion resistance: made of corrosion-resistant raw materials, corrosion resistance to the atmosphere, seawater and other corrosion resistance. Can extend the use of oil and gas transmission pipelines, deep well oil pipe time.
High-strength low alloy steel according to its main properties and uses, can be divided into three categories of high-strength steel, low-temperature steel and corrosion-resistant steel.
High-strength steel: this type of steel in addition to high strength also has excellent low-temperature toughness, used in ships, vehicles, pressure vessels, boilers, pipelines, transmission towers, bridges, lifting machinery and other welding components
Low-temperature steel: they belong to the ferritic low-temperature steel. By improving the purity of steel and reduce the phosphorus and sulfur content in the steel to get a lower toughness – brittle transition temperature, used to make low-temperature equipment parts.
Corrosion-resistant steel: these steels have a certain degree of corrosion resistance to the atmosphere, seawater, hydrogen sulphide and other environments, and are used for ships, sheet piles and derricks.
Machinability: can be machined into bolts, screws, and studs, sometimes containing small amounts of tellurium or selenium. These elements form many inclusions which are normally avoided but are necessary in this application as they break down the dangerously long strings of metal normally formed during machining into small chips. This extends product life and allows machining at higher speeds.
Hardenability: high-strength low-alloy steels are wear-resistant, which in turn creates a large amount of disturbance on impact, effectively preventing dislocation flow. In other words, the more impact a high-strength low-alloy steel is subjected to, the stronger it becomes
What are the applications of Gnee High Strength Low Alloy Steel?
For automotive body panels
High-strength low alloy steel can be used in the manufacture of automotive bodies and other parts, with good deformability and low yield limit, often instead of soft steel used as automotive exterior panels, in order to achieve weight reduction and thinning of automotive parts. cold rolled anisotropic steel has good press formability and dent resistance, is commonly used in the production of automotive body panels, and can improve the strength and safety of the body.
High-strength low alloy steel can be used for shipbuilding, can reduce the weight of the ship, not only has good plasticity, toughness, low aging sensitivity, and processing performance is good, can withstand atmospheric and seawater corrosion is commonly used in engineering machinery and ship structure manufacturing advanced high-strength steel is mainly strengthened through the phase change of the steel, its strength level is higher than the traditional high-strength steel, and has a lower yield to strength ratio and a good touch of hiding energy absorption.
High-strength low alloy steel can be used for the manufacture of gas pipelines and oil pipelines, welding performance, cold and hot processing performance and corrosion resistance are good, comprehensive mechanical properties, can improve the strength and corrosion resistance of the pipeline.
What Services Gnee Provide?
Dimensional measurements: length, width, and other parameters are measured using specialized measuring tools to guarantee production requirements.
Thickness Measurement: usually using traditional vernier calipers or digital calipers, measurements are taken at different points along the steel plate to obtain the thickness to ensure that quality requirements are met.
Surface Measurement: measurement of surface flatness and surface roughness and other parameters to meet product requirements.
Tensile test method: the steel plate is made into a standard specimen and is subjected to a tensile test on a tensile testing machine, where the yield strength of the steel plate can be obtained by measuring the stress and strain curves of the specimen.
Material Measurement: use professional instruments to analyze the chemical composition, mechanical properties and other parameters for analysis, to ensure the safety and reliability of raw materials.
Hardness test method: use a hardness tester to carry out a hardness test on steel plate material, and the yield strength can be deduced through the hardness value.
