Gr2 Titanium Cladding Steel Q235B plate for chimney
Titanium clad steel plate means make the titanium cladding on the steel plate, it is widely used in various fields due to their economic and functional characteristics. In particular, titanium steel composite materials having excellent strength, thermal conductivity, weldability and good corrosion resistance of titanium at the same time have more application prospects as structural members in marine and coastal land. The composite sheet is produced by hot rolling method, the product has large dimensional freedom, good surface quality, high dimensional accuracy and high productivity.
Tensile: The specified minimum tensile strength of the base steel should be more than 380 MPa.
Shear Strength Test: The shear test shall be carried out as per Clause 7.2.1 of ASTM A264. The shear strength of the cladded plate shall not be less than 140 Mpa.Ultrasonic Testing:The cladded plate shall be examined ultrasonically as per ASTM A578, Total non-bonded area not to exceed 2% of the total cladded surface areaHeat Treatment:Cladded plates shall be stress relived by Heat Treatment(as per supplier
Three bend tests shall be made with the cladding metal in compression to determine the quality of the bond. These bend tests shall be made in the manner of the tension tests indicated in Fig.2 of ASTM A264 and shall be bent through an angle of 180° to the bend diameters provided in either ASTM A6/A6M or specification ASTM A20/A20M. At least two of the three tests shall show not more than 50% separation on both edges of the bent portion.
's procedure).Quality Assurance Requirement:The manufacture shall conduct all the tests required in this specification to ensure that the cladded plates offered conform to this specification.
