ASME SA516 Grade 70
ASME SA516 Grade 70 – one Masteel’s most popular steel grades, the material is highly sort after for welded fabrication in industrial pressure vessels and boilers.
Used throughout the oil, gas and petrochemical industry the material is a normalized steel with excellent weldability and improved notch toughness i.e. the materials ability to absorb energy when a flaw is present.
We keep this material in stock with added stringent restrictions applied to the chemical, mechanical and testing requirements – this ensures that the material is available to you from our warehouse, regardless of your requirements.
