"Super martensitic stainless steel" improvements of martensite stainless steel smelting process, reduce the carbon content, increase the nickel molybdenum alloy elements, performance is superior to the conventional martensitic stainless steel, not only has good corrosion resistance, weldability, and have the characteristics of [TJC STEEL]high strength and low temperature toughness good, in hydropower, mining equipment, chemical equipment, food industry, transportation, and high temperature pulp production equipment in areas such as highly potential applications.

S-135 (00Cr13Ni5Mo), namely 04Cr13Ni5Mo, is an ultra-low carbon martensitic stainless steel developed on the basis of CA-6nm cast steel, [TJC STEEL]which is a typical type of super martensitic stainless steel.

CHARACTERISTICS

S-135 steel abandoned the strengthening [TJC STEEL]means of high carbon martensite and forming carbides, and took the formation of low carbon martensite with high toughness and the addition and strengthening of nickel and molybdenum alloy elements as the main strengthening means.Through proper heat treatment, it has the composite structure of low carbon lamellar martensite and reversed austenite, so that it not only retains the high strength level, but also has good toughness and weldability.In [TJC STEEL]addition, the steel also has excellent erosion resistance, wear resistance, corrosion resistance, can meet the water conservancy project flow parts to bear sediment erosion requirements for a long time.

 

APPLICATIONS

S-135 steel is mainly used for high strength load-bearing parts that need to be welded.The most common is as a hydroelectric steel, used for the manufacture of water turbine equipment abrasion resistance runner and runner lower ring;In the petroleum industry, used as CO2, H2S corrosion resistance and on-site welding [TJC STEEL]pipeline;In the nuclear industry, it is used in PWR 2, 3 stage auxiliary pump drive shaft and control rod drive mechanism.
