Supply SM55 steel mills quality specifications of stock

CM55 has good polishing performance, excellent discharge performance. 1. After the treated surface is very good, which may be substituted etching embossing. 2. After performing discharge (EDM) machining, surface hardness does not increase, simplify subsequent . homogeneous processing program, the most suitable for precision machining eclipse flower, good toughness, excellent mechanical properties. Features: 1. Pre-hardened steel, without any good pre-hardened steel heat treatment 2. 3. discharge machining characteristics best suited for mirror-polishing process . ⑴ surface after treatment is very good, which may be substituted Etched ⑵ performing discharge machining (EDM) process, the surface hardness is not increased, even to simplify the subsequent processing step 4. Organization, ideal for precision etching embossing 5. good weldability, table scraps will not harden, then the process can simplify 6. excellent toughness. Excellent mechanical properties, reducing breakage and other issues to worry purposes: 1. mirror polished mold, dust cover, TV filter plate, cosmetics boxes; 2. Precision corrugated mold, office automation equipment, automotive parts; 3. EDM Die applications: 1. The mirror-polished mold: caps, transparent shell mold appliances, cosmetics containers 2. precision machining equipment striae: office automation equipment, automotive parts following Main: structural steel: Q195, Q215, Q235-A, B, C , D, 05F, 08F, 10F, 15F, 10 # steel, 15 #, 20 #, 25 #, 30 #, 35 #, 40 #, 50 #, 55 #, 60 #, 65 #, 70 #, 75 # 80 #, 85 #, etc., tool steel: Cr12 CR12MOV 4CR13 3CR17MO 718,718H, S136, S136H, 8407, DF-2 H13, P20, etc ... 20Cr, 30Cr, 35Cr, 40Cr, 45Cr, 50Cr, 38CrSi, 12CrMO, 15CRMO , 20CRMO, 30CRMO, 30CRMOA, 35CRMO, 42CRMO, 12CRMOV, 35CRMOV, 12CR1MOV, 25CR2MOVA, 25CR2MO1VA, 38CRMOAL, 40CRV, 50CRVA, 15CRMN, 20CRMN, 40CRMN, 20CRMNSI, 25CRMNSI, 30CRMNSI, 30CRMNSIA, 35CRMN Sweden (Assab) K100, DF-2, XW-10, XW-5, XW-41,618,618H, 718,718H, S136, S136H, 8402,8407,8416, QRO-90, HSP-41, ASP23, ASP30, ASP60, VANADIS- 4, VANADIS-10, HOTVAR, 168S, 635, ASSAB88, ELMAX, XW-42, V-4, S-7, EM2, VANCRON 40, RAMAX2, POLMAX, UNIMAX, NIMAX, MM40, MMXL, ELMXX, DIEVAR, Germany (Sa Site) P20,2311,2738,2316,2083,2767,4125,2344,2367, 2379,2842,2363,2436,2510,3343,3207, TSP4,6582,7225,1293,1285, YE2311, YE2738 , YE2083, YE2316, YE2344,1.8519,1.8550,1.3243,1.3247,1.2101,1.1545,1.2080,1.2312,1.2734,1.2840,1.2842,1.2885,1.2601,1.2606,1.2714,1.1210,1.7147,1.6523,1.6582,1.5919,1.5752 SIA, 20CRMNMO, 40CRMNMO, 20CRMNTI, 30CRMNTI, 20CRNI, 40CRNI, 45CRNI, 50CRNI, 12CRNI2,12CRNI3,20CRNI3,30CrNi3,37CrNi3,12Cr2Ni4,20CR2NI4,20CRNIMO, 40CRNIMOA, 18CRNIMNMOA, 45CRNIMOVA, 18CR2NI4WA, 25CR2NI4WA, 45H, 15CrH, 20CrH, 40CrH, 45CrH, 16CrMnH, 20CrMnH, 1CrMnBH, 17CrMnBH, 40MNBH, 45MNBH, 20MNVBH, 20MNTIBH, 15CRMOH, copper: T1 TU2 TP2 H90 H96 H85 H80 H70 H68 H65 H63 H60 H62 HPb63-3 HPb63-0.1 HPb60-2 HPb59-2 HPb59- 1 HPb58-2.5 C3604 CuZn39pb3 CuZn39pb2 C2680 C1020 C1100 other copper.
