The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel Q355GNH Z tensile properties products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the Q355GNH Z tensile properties market and has strong competitiveness.

ASTM A514 steel is mainly used in places where high tensile strength and high yield are required, such as engineering vehicle lifting gears, large excavators, offshore platforms, etc. Different grades of A514 steel plate have different thickness, chemical composition and properties. However, the Q355GNH Z tensile properties mechanical properties specified in ASTM A514 are similar to those of Q690 in China. A514 grade Q is generally used as the rack for offshore platform. Its hardness is between 230-390MPa, yield is greater than 630MPa, and tensile strength is more than 700MPa.

The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The Q355GNH Z tensile properties, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.

The addition of Ca element in steel such as Q355GNH Z tensile properties can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.

SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to Q355GNH Z tensile properties ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel.
