ASME SA-213/SA-213M Grade TP 316N Material Machining Technology
Weldability is an important property of engineering and construction materials, as it determines how easy it is to join two pieces of the material together by welding. ASME SA-213/SA-213M Grade TP 316N steel is highly weldable due to its low carbon content. This low carbon content makes it easier to achieve good weld quality, and it also reduces the chances of 'hot cracking' – a type of welding defect. Grade T-14 steels have particularly good weldability, while grade T-12 steels have slightly poorer weldability.
