ASME SA-213/SA-213M Grade T2 Material Mechanical Properties
The most significant mechanical properties of ASME SA-213/SA-213M Grade T2 steel are the yield strength and ultimate tensile strength. The yield strength represents the amount of force that the material can withstand before it starts to deform in a permanent manner. The ultimate tensile strength, meanwhile, is the maximum tension that the steel can withstand before it starts to fracture.
The mechanical properties of the ASME SA-213/SA-213M Grade T2 steel are as follows:
| YieldRp0.2 | ≤ 647 (MPa) |

ASME SA-213/SA-213M Grade T2 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 T2 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.
