The basic principle of A514 grade Q quenched and tempered steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel A514 grade Q quenched and tempered steel products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.
Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.
For A514 grade Q quenched and tempered steel buyers, the impact of the rise and fall of A514 grade Q quenched and tempered steel prices is great. Because of the large amount of A514 grade Q quenched and tempered steel purchases and the large amount of funds involved, many A514 grade Q quenched and tempered steel purchasers will carefully consider the price issue, and some A514 grade Q quenched and tempered steel purchasers who are far away will also consider the freight issue. When the price of A514 grade Q quenched and tempered steel overall drops, a large number of A514 grade Q quenched and tempered steel buyers will hoard in large quantities. When A514 grade Q quenched and tempered steel prices rise, we should predict and stock up appropriately.
