Low carbon alloy steel, the total amount of alloy elements is generally ≦3%; the low carbon alloy steel strength is significantly higher than that of carbon steel, with better plasticity and toughness, and weldability is acceptable; low alloy steel includes carbon manganese series, carbon manganese vanadium series, shipbuilding use GL-D32 weldable steel chromium molybdenum series, chromium molybdenum vanadium series. Molybdenum and chromium molybdenum vanadium alloy steels are commonly used as materials for hydrogen corrosion resistance, high temperature sulfur or hydrogen sulfide corrosion resistance and heat resistance (sub high temperature).
Specification range of available steel shipbuilding use GL-D32 weldable steel: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates shipbuilding use GL-D32 weldable steel 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.
Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This shipbuilding use GL-D32 weldable steel method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
