Company through its own A588 grade B heavy plate website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.
Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. A588 grade B heavy plate, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).
The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, A588 grade B heavy plate. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.
The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some A588 grade B heavy plate maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.
In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.
Tokyo (Reuters) - 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 on Thursday. The Ministry of economy and industry quoted an industry survey report as saying that the demand for 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, A588 grade B heavy plate and so on steel exports in the current quarter will decline by 21.4% year-on-year.
