At the same time of doing well in A588 grade A HSLA steel plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A588 grade A HSLA steel plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a A588 grade A HSLA steel plate steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.
Specification range of available steel A588 grade A HSLA steel plate: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates A588 grade A HSLA steel plate can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A588 grade A HSLA steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A588 grade A HSLA steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
Mechanical Properties A242 steel: ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50. Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4) Yield: 50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4) Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)
