Figure 5. H11 can also be cold-worked and welded with conventional methods for steels in this group. This material may be nitrided. Nickel was first discovered by Alex Constedt in 1751. Another unique property of maraging steels is their very good weldability which basically means that it can be easily joined with other metals achieving a good level of integration on the welding points. maraging steels have characteristics including (1) good machinability attributable to formation of soft martensite in a quenched stage, (2) very high strength attributable to precipitation of intermetallic compounds, such as ni 3 mo, fe 2 mo and ni 3 ti, in martensite texture through aging treatment, and (3) high toughness and ductility in spite Applications. Prolonged exposure at these temperatures may result in some age hardening. The melting point of low alloy steel is 1432C (2610F) and the same for high alloy steel is 1415 . Tool Steel H11 can be easily formed using conventional methods for machining and forging. There are five types of stainless steel, viz., austenitic, ferritic, martensitic, precipitation-hardening martensitic, and duplex stainless steel. Strength.
