These alloy seamless steel pipes from Zhejiang Dingxin Steel Tube Manufacturing Co., Ltd. are produced from 30CrMo (4130) material, a chromium-molybdenum alloy known for its strength and toughness. The pipes are manufactured to meet international standards such as DIN 2391, DIN 1629, EN 10305-1 and ASTM A519, ensuring suitability for high-pressure and mechanical applications.
The material 30CrMo/4130 is a low-alloy steel with typical carbon content around 0.30% and chromium-molybdenum additions for improved hardenability and wear resistance. Standard wall thickness ranges from 1 mm to 32 mm, with typical outer diameters from 6 mm to 219 mm for industrial use. The seamless process ensures uniform mechanical properties, making these pipes ideal for hydraulic systems and structural components.
Primary applications include aerospace, automotive and oil and gas industries, where high-pressure resistance and durability are critical. The pipes are sourced from Zhejiang, a major steel production region in China, and are shipped in secure packaging to prevent damage. Buyers are advised to confirm MOQ, incoterms and inspection requirements directly with the supplier.

Before placing an order, confirm the exact grade and standard to ensure the pipes meet your project’s mechanical and chemical requirements. Request third-party inspection reports to verify compliance with DIN, EN or ASTM specifications, as these are critical for high-pressure applications.
Discuss incoterms such as FOB Ningbo or FOB Shanghai, as Zhejiang’s proximity to these ports can influence shipping costs. Lead times for 30CrMo pipes may vary based on diameter and wall thickness, so agree on production schedules and delivery timelines. Payment terms should be clarified, with options like L/C or T/T typically available.
Quality control should include visual inspection for surface defects, dimensional checks against standard tolerances and non-destructive testing for internal integrity. Ensure all packaging meets export standards to prevent corrosion or damage during transit. Verify that the supplier provides complete documentation, including packing lists and certificates of origin.
