Chemical and mechanical properties of 09CuPCrNi-B grade steel
The basic principle of 09CUPCRNI-B grade steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
Our main specifications of medium and heavy plates are thickness 6.0-180mm and width 1400-2700mm. In addition, the ship steel plate has been approved by the factories of the eight-nation classification society such as CCS, ABS, BV, LR, GL, NK, KR, and DNV. Our 09CUPCRNI-B grade steel, medium and heavy plates are widely used in manufacturing, logistics, and automotive industries such as construction machinery, mold processing, ships, bridges, high-rise buildings, pipeline transportation, automobile girders, automobile bridge shells, and pressure vessels.
Hot Rolled Plates 09CUPCRNI-B grade steel MachiningAfter final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.
There are various weather resistant steel materials in the world. Their thickness ranges are distinct. For JIS G3125 weathering steel sheet, typical grades are SPA-H / SPA-C, the max. thickness is 16mm. For TBT 1979 weather resistant steel sheets, typical grades are 09CuPCrNi-A / 05CUPCRNI, the max. thickness is 20mm. For EN 10025-5 steel, typical grades are S355J0WP / S355J2WP / S355J0W /S355J2W, the max. thickness is 100mm. The max. thickness for 09CUPCRNI-B grade steel, ASTM A588 steel plate is 200mm. And the max. thickness for ASTM A242 steel plate is 100mm.
