2020.11.30 hardness of S690QL price per kg

The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with hardness of S690QL good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the hardness of S690QL, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.

The difference between Q195 steel and 20# steel: hardness of S690QL, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. hardness of S690QL heat treatment process refers to the ability to change the microstructure and properties of hardness of S690QL after heat treatment, including hardenability, hardenability, temper brittleness, etc

Our produced Grade A normal strength shipbuilding steel are certified by CCS, BV, LR, ABS, DNV, GL, KR and NK ABA/ ABS Grade A marine steel plates are suitable for use in the construction of container ships and large cargo freighters and commercial shipping lines such as luxury cruise ships and ferries,hardness of S690QL., ABS Grade A Steel Plates Size and Specification Thickness: 3~150mmWidth: 1219~3200mmLength: 2500~12000mm

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
