SA387 Gr 11 Cl 1 steel has high brittle resistance, and also has good impact toughness in low temperature environments. It is suitable for refining and gas treatment in hydrogenation reaction and conversion equipment at high temperature. The maximum thickness of P235GH grade standard products can reach 250mm. According to different thickness and impact requirements, the heat treatment of A387 Gr 11 Cl 1 plate can choose normalizing and tempering or normalizing and rapid cooling and tempering.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. p235gh grade standard, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

Ultrasonic flaw detection emits ultrasonic waves to the p235gh grade standard steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the p235gh grade standard steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
