40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. JIS SM490B plates, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
After extrusion, the JIS SM490B plates tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
According to the separate performance report released by India's Jindal stainless steel (Sisal) Co., Ltd. (JSHL), as of March 31, 2020, due to the global economic slowdown, epidemic situation, imports and other factors, its JIS SM490B plates stainless steel sales decreased by about 10% to 600000 tons from 667000 tons in the previous fiscal year, and its net sales decreased by nearly 7% to 83.396.9 billion rupees, with the same gross operating profit (EBITDA) After tax profit increased by 22.4% to 3.203 billion rupees. The adoption of the new tax system has a positive impact of RS 220 million on after tax profits.

Japan's crude steel production is expected to fall 25.9% in the April June quarter from a year earlier, the Ministry of Economy, Trade and Industry said Thursday. The Ministry of Economy and Industry quoted an industry survey report as saying that the demand for JIS SM490B plates and so on steel products (including export products) in April June is expected to drop 18.1% to 18.28 million tons from the same period last year. At the same time, steel exports in the current quarter will decline by 21.4% year-on-year.
