从China供应商批发进口4140 /42crmo Round Bar — FOB条款

Jiangsu Zhuhong Forging Co., Ltd. supplies 4140 and 42CrMo4 alloy steel round bars in chromium molybdenum composition, with carbon content between 0.38 and 0.45 percent, manganese at 0.60 to 0.90 percent, chromium at 0.80 to 1.10 percent, and molybdenum at 0.15 to 0.30 percent. The bars are forged to diameters of 130 mm to 1200 mm and delivered in lengths starting at 4 metres, available in black surface, turned, or heat-treated condition.

This grade is a standard chromium molybdenum alloy steel used extensively in machinery manufacturing, oil and gas equipment, and heavy industrial applications due to its high strength, toughness, and wear resistance. The material typically achieves a grain size better than 5 as per ASTM E112-96, and ultrasonic testing follows SEP 1921 Group 3 Class C, D, or E standards to ensure internal integrity. Typical hardness in the heat-treated condition ranges from 28 to 32 HRC, depending on the thermal process applied.
