The use of 7MN15CR2 non-magnetic steel has been widely used in many electrical products: 1, large and medium-sized transformer oil tank magnetic shield, iron core pull plate, coil clamp, bolts and other magnetic field leakage structure; 2, large and medium-sized generator stator coil tie ring, retaining ring, tooth pressing parts and other structural parts; 3. High-voltage bushing parts of high-voltage and high-current transmission lines and adjacent steel structure frames; 4. Special smelting electric furnace lining, furnace cover, electrode splint and electronic stirring device structural parts; 5. magnetic separation equipment cylinder, box selection, iron remover and lifting electromagnet; 6, navigation compass and electrical instruments and other industries What are the common problems of 7mn15cr non-magnetic steel? Use of 7mn15cr2, price of 7mn15cr2,
Q: What material is 7MN15CR2? A: Mn15Cr2Al3V2WMo steel is a high Mo-V non-magnetic steel. The steel can maintain stable austenite in various States, and has very low permeability coefficient, high hardness, strength and good wear resistance Q: What is the difference between 7MN15CR2 and imported HPM75? A: 7Mn15Cr2Al3V2WMo has a very low permeability coefficient, and HPM75 is completely non-permeable;
Q: What is the HRC hardness of 7MN15CR2? Tube: factory hardness HRC28-30 degrees, and solution treatment hardness HRC42-45 degrees; Chemical composition of 7MN15CR2? Answer: C: 0.65 ~ 0.75 Si: ≤ 0.80 Mn: 14.5 ~ 16.0 P: ≤ 0.04 S: ≤ 0.03 Cr: 2.0 ~ 2.5 Mo: 0.5 ~ 0.8 W: 0.5 ~ 0.8 V: 1.5 ~ 2.0 Al: 2.7 ~ 3 Q: What is 7MN15CR2 used for? Answer: 7MN15CR2 This steel is suitable for manufacturing non-magnetic dies, non-magnetic bearings and other structural parts that require no magnetic induction in strong magnetic fields. Q: Is 7MN15CR2 the same as stainless steel 304? A: 7MN15CR2 is a non-magnetic material for mold, while 304 material is a real stainless steel series; Q: What is the price of 7MN15CR2? Answer: 7MN15CR2 non-magnetic steel is divided into two kinds of raw materials and clinker (good solution treatment); The existing illegal manufacturers use stainless steel instead, which causes many manufacturers to purchase materials twice, thus increasing the original cost. Q: What is the heat treatment method for 7MN15CR2 non-magnetic steel? Answer: 7MN15CR2 heat treatment is divided into two types: 1) solution aging treatment; 2) decarburization treatment. Q: What is the difference between 7MN15CR2 and 5CR21 materials? Answer: 7MN15CR2 has the physical characteristics of good plasticity, high toughness, great work hardening tendency, large thermal expansion coefficient, large resistivity, low thermal conductivity and low magnetism. 5CR21 is used to replace 7MN15CR2, and its performance is much worse than 7MN15CR2.
