The steel plate for water conservancy and power generation is used for ring seat, motor support structure, ship lock gate and discharge chute volute of large water conservancy generating units; the representative steel grades are S500Q, S550Q, SA516, etc., which require flaw detection and have Z-direction performance requirements; the main specifications are thickness of 120mm, 180mm, 200mm, 215mm, 270mm, and the maximum width is 4400mm. The representative steel grades of wind power steel plates include Q345E, Q690E, ASTM A588 HSLA steel plate, etc.; the main specifications are thickness of 80mm, 100mm, 110mm, 120mm, 140mm, 160mm, 180mm, 200mm, 240mm, 260mm, 280mm, 300mm, and the width is more than 2500mm.
35# steel is a high-quality medium carbon carbon structural steel, with good plasticity and appropriate strength, good process performance, and acceptable welding performance. It ASTM A588 HSLA steel plate is often delivered in normalized and tempered state. 35 # steel is widely used in the manufacture of various forged and hot-pressed parts, cold-drawn and ASTM A588 HSLA steel plate upset forged steel, seamless steel tubes, and parts in machinery manufacturing.
Titanium microalloying is an element of ASTM A588 HSLA steel plate strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in ASTM A588 HSLA steel plate tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
