20cm S690QL material data sheet

Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe, S690QL material data sheet. Seamless pipe supply scope is OD 10.3mm--965.2mm, wall thickness 1.0mm--60mm. The ERW pipes production range from OD 21.3mm--660mm, wall thickness 1.0mm--16mm. LSAW pipes can supply with OD 406mm--1524mm, wall thickness 6mm--50mm. SSAW pipes can produce maximum OD 3500mm, minimum OD 219.1mm, wall thickness 3.2--25.4mm.

The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, S690QL material data sheet, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.

S690QL material data sheet annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of S690QL material data sheet annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. S690QL material data sheet annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
