Development trend of 09CuPCrNi-A machinability

The company has allocated special environmental protection facilities for all 09CuPCrNi-A machinability pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, 09CuPCrNi-A machinability steel mill scale, environmental protection dust has reached 100%.

There are several grades of ferritic steel covered by A333 seamless and welded carbon and alloy steel pipe standard: Grade, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11. BBNsteel company provides ASTM A333 pipes made by the seamless or welded process with the addition of no filler metal in the welding operation except that Grade 4 shall be made only by seamless process. The pipe 09CuPCrNi-A machinability shall be furnished free of welding repair, either radiographically tested or ultrasonically examined.

S235JR steel plate is one mainly of Carbon and low alloy steel, S235JR steel plate is a type of steel sheet under EN standard which is used to build ship, bridge, belongs to high strength sheet. EN10025-2 S235JR is equivalent to DIN:ST37-2,JIS:SS400,ASTM:A283C, GB Q235B and UNI:FE360B.

During the construction of hot-dip 09CuPCrNi-A machinability galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the 09CuPCrNi-A machinability construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.

BBN steel 09CuPCrNi-A machinability 15mm to 35mm thick size: 15*2120*5620, 17.5*2320*13000, 18*2450*5500, 20*3000*5000, 19*2580*4700, 19.5*1970*4000, 20*1600*7740, 20.5*2370*7000, 21*2650*7500, 21*1920*8220, 22*1380*7650, 22*1800*8000, 22.5*1680*8450, 23*3000*11980, 23.5*2080*8100, 24*1560*6200, 25.5*2330*8300, 26*3010*8100, 26.5*2000*7000, 27*2550*6800, 27.5*2700*5500, 29*2550*9000, 29*2870*12000, 32*3300*6000, 33*2340*6700, 34*2120*6100, 35*1300*4100.
