Characteristics :

• Rm - Tensile strength; ReH - Upper yield strength; A - Elongation after fracture              
• 1Mpa=1N/mm2                                                 
• Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strength.                                                    

• For calculation purposes the following relations are recommended -                     
  
  • For delivery condition +C - ReH ≥0.8 Rm                                                 
  • For delivery condition +LC - ReH ≥0.7 Rm                                                  

• For calclulation purposes the following relation is recommended -ReH≥0.5Rm                 
• For tubes with outside diameter ≤30mm and wall thickness ≤3mm the ReH minimim values are 10Mpa lower than the values given in this Table                                
• For tubes with outside diameter 160mm - ReH≥420Mpa
