How I weld ASTM514grB "T" 1 steel

[Frank S]

Hi Frank. What is ASTM514grB "T" 1 steel?

T1 steel is a low carbon alloy that has been quenched and tempered having a tensile strength in the range of 110,000 PSi a minimum yield of around 89,000 or more depending on thickness. While it is classed as a high strength structural steel it shares little with more commonly known structural metals with the exception of being weldable machinable and formable to a limited extent. It is often used in applications where moderately high wear and or stresses are prevalent such as the manufacture of earth moving equipment Truck frames. Often used in pressure vessels just 1 step away from 516 boiler plate, and shares many characteristics as armor and wear plating such as AR 350,400 & 500.
It is a naturally hard metal having a RC of between 27&35 which can be case hardened to even higher through forging and heat treating. It is often used to make punches and dies even cutting blades for some applications not requiring higher strength more durable metals.
It is used extensively in the manufacture of heavy hauling trailers and equipment since it has a high resilience to fatigue and good return to original shape memory like spring steel.
People who have known and worked with me for a long time call it my kryptonite metal because when I build something out of it not even superman wants to try and break it LOL.
