The thermal expansion coefficient of copper's C, ordinary carbon steel, and martensitic stainless steel is 1, austenitic stainless steel is 1, and ordinary carbon steel is 1 meter, 1 degree, and 1 wire, that is, the temperature rise of 1 meter of steel is amplified by 1 °C, and the stainless steel is 0.
The temperature line and the expansion coefficient of the concrete line (the proportional temperature linear expansion coefficient is 1, the temperature linear expansion coefficient of concrete is 1, the expansion coefficient of steel is increased in the length direction: 10 meters * 1, complex direction: 2 meters * 1 , for more information, you can consult Shenzhen Lanqiaoying Technology Co.,LTD.
