DIN17176 Steel Tubes

We are leading manufacturer and stockist of DIN17176 steel tubes in China.DIN17176 steel tubes Field of applicationDIN17176 steel tubes for hydrogen service at elevated temperatures and pressures DIN17176 steel tubes ConceptSteel for hydrogen service at elevated temperature and pressure is steel that is not readily susceptible to decarburization by hydrogen at elevated pressures and temperatures and thus to hydrogen and grain boundary embrittlement.this characteristic is achieved by adding alloying elements that from carbides at the operating temperature.GradeMaterial numberCSiMnP      maxS      maxCrMoNiVOthers25CrMo41)      13CrMo44      10CrMo910      12CrMo910      12CrMo1210      12CrMo195      X12CrMo91      20CrMoV135      X20CrMoV121    1.7216      1.7335      1.7380      1.7375      1.7381      1.7362       1.7386       1.77791.49220.22-0.29      0.10-0.182)      0.08-0.15      0.10-0.15      0.06-0.15      0.08-0.15      0.07-0.15      0.07-0.23      0.17-0.23≤0.40      0.10-0.35      ≤0.50      ≤0.30      ≤0.50      ≤0.50      0.25-1.00      0.15-0.35      ≤0.500.60-0.90      0.40-1.00      0.40-0.70      0.30-0.80      0.30-0.60      0.30-0.60      0.30-0.60      0.30-0.50      ≤1.000.035      0.025      0.025      0.015      0.025      0.025      0.025      0.025      0.0250.030      0.020      0.020      0.015      0.020      0.020      0.020      0.020      0.0200.90-1.20      0.70-1.10      2.0-2.5      2.0-2.5      2.65-3.35      4.0-6.0      8.0-10.0      3.0-3.3      10.0-12.500.15-0.30      0.40-0.65      0.90-1.20      0.90-1.10      0.80-1.06      0.45-0.65      0.90-1.10      0.50-0.60      0.80-1.20-      -      - <0.30 -      -      -      -      0.30-0.80-      -      -      -      -      -      -      0.45-0.55      0.25-0.35A0l≥0.010,Website:http://www.petrosteels.com,Cu<.20< p="">.20<1)At the manufacturer’s discretion,grade 24CrMo5,material number 1.71258,may be substituted for grade 25 CrMo 42)For wall thicknesses not less than 30 mm,the carbon content may be up to 0.02% higher. The types of DIN17176 steel tubes  DIN17176 ST35 steel pipes  DIN17176 ST52 steel pipes  DIN17176 25CrMo4 steel tubes  DIN17176 13CrMo44 steel tubes  DIN17176 10CrMo910 steel tubes  DIN17176 12CrMo910 steel tubes  DIN17176 12CrMo1210 steel tubes  DIN17176 12CrMo195 steel tubes  DIN17176 X12CrMo91 steel tubes  DIN17176 20CrMoV135 steel tubes  DIN17176 X20CrMoV121 steel tubes  DIN 17177 STEEL PIPES  DIN 17178 STEEL PIPES DIN 17179 STEEL PIPESONE OF THE KIND, MILLIONS OF CHOICES  SUPERIOR QUALITY  PROMPT DELIVERY  FAVORABLE FEEDBACK  ALL AVAILABLE IN PESCO  SELECT PESCO, YOU WILL BE RIGHTFor more info and price of DIN17176 steel tubes, please send us inquiry and you will have quick reply soon.
