As the thickness and hardness of GL-A32 steel wide flats increase, the tendency to crack at the cutting edge increases. In order to prevent the GL-A32 steel wide flats from cutting cracks, preheating should be carried out before GL-A32 steel wide flats cutting. Special attention should be paid to preheating to make the entire GL-A32 steel wide flats interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole GL-A32 steel wide flats cannot be preheated, the partial preheating method can be used instead.
The yield strength of GL-A32 steel wide flats A32, D32, E32, F32 is not less than 315N/mm^2, and the tensile strength is 440~570N/mm^2. The grades A, D, E and F indicate that they can be 0 and -20 respectively. The impact toughness can reach -40℃, -60℃.
Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe, GL-A32 steel wide flats. 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.
Training is one of the important factors in the construction of corporate culture. Online training system can be used to enable all employees to take advantage of fragmented time and carry out targeted training anytime and anywhere without the limitation of time and region. Through training to improve work skills, at the same time, through training, let all improve their quality education level, let employees work around a goal, create a career, and produce results.
