ASTM A333 Grade 1 Seamless and Welded Steel Pipes

ASTM A333 Grade 1 carbon steel pipes (available seamless and welded) engineered for reliable performance in low-temperature and other notch-sensitive applications. These pipes are produced to ASTM/ASME requirements and offer a balance of ductility and strength with low carbon content and controlled manganese for improved toughness.

Key features

• Specification: ASTM A333 Grade 1 (ASME SA333 Grade 1) — suitable for low-temperature service and applications requiring good impact (notch) toughness.
• Construction: Available in both seamless and welded manufacturing methods.
• Materials: Carbon / ferritic steels offered to relevant international equivalents (can be supplied to ASTM, DIN, EN, JIS, BS, API, GB standards where specified).
• Dimensions: Outer diameters typically from 1/8" up to 36" (3.2 mm to 914 mm). Wall thicknesses offered from light schedules (SCH5) through XXS/heavy wall variants.
• Lengths: Standard supply lengths for container shipping — approx. 6 m to 12 m (8 m typical for 20' container loads); custom lengths available on request.
• Quality & inspection: Third-party inspection and certification available (BV, CE, SGS, Lloyd’s Register, DNV, CCS, etc.).

Typical applications

• Low-temperature piping systems and cryogenic service
• Oil & gas gathering, transport and processing
• Pressure piping and boilers where notch toughness is required
• Structural and mechanical applications in cold environments

Supply options & ordering

• Material certificates and test reports available on request (chemical analysis, mechanical tests, impact tests).
• Available in multiple international grades and equivalents; special end preparations (beveling, threading, coating) and cutting/packing for export can be arranged.
• For pricing, lead times and MOQ, request an RFQ through the marketplace quoting required standard, size (OD × wall), length, quantity and inspection requirements.

If you need assistance matching ASTM A333 Grade 1 to other international grades or specifying end finishes and inspection plans, include those details with your RFQ so suppliers can provide accurate offers.
