High Strength Stainless Steel Belt

 

Mingke MT1650 (previous model: MK-1650SM) is a low carbon precipitation-hardening stainless steel that provides high strength and hardness, good corrosion resistance and minimum distortion on heat treatment. It is easily formed in the annealed condition and develops an effective balance of properties by heat treatments. For applications requiring exceptionally high strength, MT1650 Stainless Steel in Condition CH 900 is particularly useful for applications with limited ductility and workability. High strength is maintained to approximately 600°F (316°C).

Dynamic Strength

The fatigue limit is defined as the reverse bending stress at which 50% of the test specimen withstand a minimum of 2x106load cycles. These values refer to 20° C (68° F), a normal dry atmosphere and standard prepared specimen. The fatigue limit for the parent material is approximately ± 630 Mpa (91 Ksi).

 

Corrosion Resistance

The general level of corrosion resistance of MT1650 stainless steel exceeds that of Types 410 and 431, and is approximately equal to that of MK 630 stainless steel. This is indicated by laboratory tests in both strongly oxidizing and reducing media, as well as by atmospheric exposures. In all heat-treated conditions, this alloy exhibits very little rusting after 500 hours exposure to 5% salt fog at 95 °F (35 °C). When exposed to seacoast atmospheres for long periods of time, the material gradually develops a superficial layer of rust like other precipitation-hardening stainless steels. The general level of corrosion resistance is best in the fully hardened condition, and decreases slightly as the aging temperature is increased.

 

Weldability

The precipitation hardening class of stainless steels is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to achieve optimum mechanical properties by considering the best heat-treated conditions in which to weld and which heat treatments should follow welding. This particular alloy is generally considered to have equivalent weldability to the most common alloy of this stainless class MK 630 Stainless Steel. TIG welding is the best way, and ER632/ER630 are the optimal welding wire. Mingke is capable of heat treatment for welding line on site, and the welding factor can reach 1.
