High Strength Stainless Steel Belt

 

Mingke MT1500 (previous model: MK-1500SM) precipitation hardening stainless steel, is a chromium-nickel-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600°F (316°C). The MT1500 alloy is martensitic in structure in the annealed condition and is further strengthened by a low temperature treatment which precipitates a copper containing phase in the alloy.

Dynamic Strength

The fatigue limit is defined as the reverse bending stress at which 50% of the test specimen withstand a minimum of 2x106 load 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 ± 580 Mpa (84 Ksi).

 

Corrosion Resistance

MT1500 Stainless Steel provides excellent corrosion resistance. It withstands corrosive attack better than any of the standard hardenable stainless steels and is comparable to Type 304 in most media. This has been confirmed by actual service in a wide variety of corrosive conditions in the petrochemical, petroleum, paper, dairy and food processing industries, and in applications such as boat shafting. Additional proof of its durability is the replacement of chromium-nickel stainless steels and high-alloy non-ferrous metals by this alloy for a broad range of parts requiring excellent resistance to corrosion.

 

Weldability

Mingke MT1500 precipitation hardening stainless steel is readily welded using conventional inert gas methods used for stainless grades. Preheating is not usually required. Postweld heat treating is needed to produce the various precipitation hardened heat treatment properties.

If matching filler material is used, properties comparable to those of the parent metal can be produced in the weld by postweld precipitation hardening heat treatment. Mingke is capable of heat treatment for welding line on site, and the welding factor can reach 1.
