For kitchen knife blades and utensils used in food preparation, we recommend either the MA3M grade, which contains molybdenum, or the MA5 grade, which has a high chromium content. Show Martensitic Stainless Steel materials with Hardness, Brinell of 230 [-] at 20 °C. 420 stainless steel “Blade grade” martensitic steel, the earliest stainless steel, similar to Brinell high chromium steel. MA5: martensitic stainless steel with a high degree of hardness and improvedresistance to corrosion for knife blades and cutting tools 230 [-] at 20 °C. The notable properties of … Martensitic stainless steels can be heat treated and hardened, but have reduced chemical resistance when compared to austenitic stainless steels. Stainless Steel - Martensitic - 1.4125 (440C) Bar. DSM-0257.0 – Martensitic Stainless Steel Powders ©2020 Oerlikon Metco 1 Powder Products: Metco 42C, Diamalloy 1002 1 Introduction Diamalloy™ 1002 is a martensitic chromium stainless steel powder, similar to type 420 stainless steel. SUS420F is a stainless steel type which improves the cutting performance of SUS420J2 steel. Martensitic stainless steel is an alloy which has more chromium and ordinarily no nickel in it. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. The mechanical values apply to the heat-treated condition. Overview. In stock and ready to ship. 4Cr13 Stainless Steel Introduction 4Cr13 steel (New name: 40Cr13) is a martensitic type stainless steel, which has higher hardness than 3Cr13 steel after quenching. Once heat treated, the alloy has excellent hardness properties and is suitable for use in stressed parts. Martensitic stainless steels are low carbon steels built around the Type 410 composition of Iron, 12% to 15% Chromium, and 0.08% to 0.50% Carbon. It has been opti-mized for wear resistance while still offering fairly good corro- They do provide some corrosion resistance; however are not as resistant as the austenitic grades. Martensitic stainless steel with a relatively high carbon content. SS 440A, 440B and 440C stainless steel are AISI and ASTM standard high carbon high chromium martensitic stainless steel, SS440 has high strength, good hardness, corrosion resistance, wear resistance and high temperature dimensional stability. This specification covers martensitic chromium stainless steel forgings, forged bars, and forging stock for high-temperature service. Alloy 410 stainless steel plate is the general purpose 12% chromium martensitic stainless steel that can be heat treated to obtain a wide range of mechanical properties. 440c Martensitic Stainless Steel. The mechanical properties are developed by suitable heat treatment, as indicated for each alloy. Martensitic Stainless Steels These grades offer better erosion or wear resistance because of the high hardness values that can be obtained through heat treatment. 410 stainless steel is a hardenable martensitic stainless steel alloy. 410 alloy is required when strength, hardness and wear resistance is required with some corrosion resistance. Martensitic stainless steel's strength and corrosion resistance are ideal for marine, industrial, and medical applications while its versatility can make it the solution to a number of problems. Choose from our selection of martensitic stainless steel, including easy-to-machine 416 stainless steel, bearing-quality 440C stainless steel, and more. The martensitic steel are plain chromium steel containing between 12% and 18% chromium, can be heat treated to obtain high strength with good ductility. Although it was a disadvantage that martensitic stainless steel was difficult to process because of its hardness, our company repeatedly Grade 440C stainless steel is a high carbon martensitic stainless steel. Martensitic stainless steel is indispensable to keep sharpness for a long time. 1.4125 (440C) Bar. R m. 700 - 950 MPa at 20 °C. Alloy 410 is the basic, general purpose martensitic stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness. It is also used for surgical cutting tools, which can be very bright. Similar to 410, it contains a minimum of 12% chromium, just sufficient enough to give corrosion resistant properties.
