Carbon & Low-Temperature Carbon Steel — A106, SA516, A333, API 5L, 09G2S
The workhorse structural and pressure-bearing steels — including low-temperature grades for LNG and cryogenic service — with full certification.
Carbon steel remains the backbone of piping and structural work. We supply seamless and welded carbon-steel pipe (A106, API 5L), pressure-vessel plate (SA516), and low-temperature service grades (A333 Gr.6/3/8, 09G2S) that retain toughness down to -46°C and below. All material comes with EN 10204 3.1 certificates and impact testing where required.

Industries: Oil & gas pipelines · Pressure vessels · LNG & cryogenic terminals · Structural & offshore · Boilers & refineries · General engineering.
A: A333 Gr.6 covers down to -46°C; for lower temperatures use A333 Gr.3 (-101°C) or Gr.8 (-196°C), or 09G2S for structural low-temp use.
A: A106 is a piping specification for refinery/plant service; API 5L is the line-pipe specification for pipelines, with additional requirements for weldability and toughness.
A: Yes — SA516 with HIC (NACE TM0284) and SSC (NACE TM0177) testing can be arranged for sour-service projects.
