Steel HCM 12 (no. 7) is a newly developed Japanese 12% Cr steel with 0.10% C 1% Mo 1% W 0.25% V 0.05% Nb 0.03% N and a duplex structure of delta ferrite and tempered martensite with improved weldability and creep strength.3CR12 Stainless Steel3CR12 is a low cost utility stainless steel providing benefits of strength, corrosion and abrasion resistance, durability and low maintenance. 3CR12 is similar to grade 409 and grade 410S (nominally 12% chromium) so it exhibits similar corrosion resistance properties, and has many advantages in terms of fabrication and mechanical properties.DATA SHEET B 10Plain 12%Cr steels are the most simple and economic alloys with stainless properties. Variants with Ti (409), Al (405) or low carbon (410S) are more or less fully ferritic with typically lower strength than type 410. These types, and the newer "utility ferritics", are normally welded without PWHT using 309/309L consumables (data sheet B 50).

The Japanese steel NF616 is a tungsten alloyed 9%Cr steel, which was invented by Prof. T. Fujita at Tokyo University in the middle of the 1980´s based on life long studies of the 9 12%Cr steels. Further development of the steel was made together with Nippon Steel Corporation [1,2].Cr12 Steel Chemical composition, Metal Properties 21 rows· Cr12 can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, See all 21 rows on steel gradesAPI Material Classification PowerZoneCarbon SteelInternal Parts 12% CrShaft AISI 4140Impeller 12% CrS 8.

steels. They are plain chromium steels containing between 12 and 18% chromium. The stainless steel is of moderate corrosion resistance which can be hardened by heat treatment resulting in high strength and hardness. Due to the high Carbon content of the steel it responds well to heat treatment to give various mechanical strengths, such as hardness.12% Cr steels The steam turbineA typical steel is FV 448, an 11% Cr, 0.6% Mo, 0.25% V, 0.3% Nb steel with good creep resistance up to 550°C. The corrosion and scaling resistances of the latest so called 'Super 12% Cr' steels are at least equal to those of the simple 12% Cr steels and in many cases significantly better.Abrasion Resistant Cast Iron 12% Cr Casting Material Aug 08, 2013· 12% Cr is a populuar abrasion resistant cast iron in ASTM A532 standard, it is also one type of White Iron. 12% Cr chemistry requirement in ASTM A532 Standard Sepcification for Abrasion Resistant Cast IronsClassII castingquality TypeA Designation12% Cr Carbon2.0 3.0% Manganese2.0% max Silicon1.5% maxcastingquality Cast Iron Pump Impeller with

A new 12% chromium steel strengthened by Z phase

of 9 12% Cr steels at 650°C, a new alloy design concept was proposed, using thermodynamically stable Z phase (CrTaN) precipitates to strengthen the steel. A new trial Z phase strengthened 12% Cr steel was produced and creep tested. The steel exhibited good long term creep resistance.Creep properties of 12% Cr and improved 9% Cr weldments Martensitic Cr alloyed high temperature materials offer interesting opportunities for design and construction of advanced power plants. An extensive research programme has been carried out at the Research Centre of the Belgian Welding Institute and Laborelec on martensitic 12% Cr steel for gaining a better understanding of the failure mode and the deformation mechanism of welded joints under Development of a new 12%Cr steel for tubes and pipes in Nevertheless, their range of use is limited for high temperature because their oxidation resistance is lower than that of the classical 12%Cr steels, such as X20CrMoV12 1 or the austenitic steels. In order to meet higher design parameters, a new steel, named VM12, has been developed by Vallourec and Mannesmann Tubes (V&M).

13CrMo4 5, 1.7335 Characteristics and application. 13CrMo4 5 low alloy steel is a relatively low carbon chrome molybdenum grade compared to other related high temperature grades, characterized by good cold and hot workingability, excellent machinability, weldability while maintaining high strength properties at room temperature and elevated temperatures.Stainless Steel Grade 3CR12 (UNS S40977)Grade 3CR12 stainless steel is a low cost grade chromium, containing stainless steel fabricated by modifying the properties of grade 409 steel. It resists mild corrosion and wet abrasion. It was originally developed by Columbus Stainless, which designated the registered trademark 3CR12.Investigation of microstructural evolution and creep The weldments made from the 912% Cr tempered martensitic steel are associated with a complex microstructure arising from complicated thermal histories of the fusion and heat affected zones. The complicated microstructural and micro mechanical states in these critical regions provide a challenge for the determination of creep failure mechanisms.
