Copper Nickel 90/10 Tube. Copper Nickel 90/10 tube is the most commonly used wrought copper alloy for marine engineering and can be found in seawater systems for naval, commercial shipping and the oil & gas markets due to its good strength, corrosion resistance and inherent resistance to biofouling in salt water environments.

Method for improving rust resistance of large-caliber steel pipe . 1.When sand blasting or manual mechanical derusting is used, the metal scale on the surface of the large-diameter steel pipe is directly exposed to the air due to the peeling of the oxide scale from the large-diameter steel pipe. If a primer is not painted in time, the surface of the large-diameter steel pipe is likely to rust Microstructure and mechanical properties of friction-stir The weld parameters used are as follows:weld speed of 65 mm/min, rotational speed of 630 r/min, and down-ward vertical force of 11 kN. A tilt angle of 3° was em-ployed in the welding trials. A schematic showing the FSW welding process, the welded plates, and the extrac-tion of the test specimens from the welded plates is given in Fig. 1. Table 1. S235JR Spiral welded pipe - ltgtsteelchinaQ345---SS500, ST52S355JR:Introduction:Spiral welded pipe:is the low carbon carbon structure steel or low alloy structure steel strip according to a certain Angle of the spiral line (called the forming Angle) rolled into the tube billet, and then the pipe seam welding up made, it can use a narrower strip steel production of large diameter steel pipe.The specification is eed by the outer diameter * wall thickness, and the welded pipe
SA517 Gr.H is a high strength quenched and tempered alloy steel plates intended for use in fusion welded boilers and other pressure vessels. The maximum thickness of plate, grade A and grade B are 32mm:Grade H and grade S are 50mm:grade P is 100mm:Grade F, is 65mm:Grade E and grade Q are 150mm in thickness ST52 / S355JR Rolled Steel Tube , Automobile High ST52/S355JR high precision cold rolled steel tube for automobile, OD:10-150mm; WT:2-25mm Overview Cold drawn seamless has closer dimensional tolerances , better surface finish and higher mechanical properties than corresponding grades of hot finished seamless. THE EFFECT OF SUBSTRATE MICROSTRUCTURE ON substrate microstructure on ironzinc alloy - layer formation was studied.To achieve different microstructures laboratory heat treatment was used. Heat treatment parameters were chosen to imitate the heat affected zone in welding and thermal cutting processes. Steel grades S355JR, S700MC, C45E and C60E with different
