The basic phases of A514 Gr Q high strength steel plate, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
Our company has a backbone team who is proficient in business and strong in operation. While providing customers with a variety of logistics solutions, we can also explore the A514 Gr Q high strength steel plate Chinese market for overseas customers to find sources of goods, inspect and accept goods, and declare customs to relieve all worries about import and export.

A36 steel plate contains different amounts of other materials such as carbon, nickel, manganese, tungsten and molybdenum. Different components in A514 Gr Q high strength steel plate A36 steel plate will produce different properties. The modulus of elasticity (i.e. hardness measurement) of all A36 plates is 29 million psi.
The quality of A514 Gr Q high strength steel plate shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of A514 Gr Q high strength steel plate buyer, such as packaging, delivery time, etc.. On the basis of the quality of A514 Gr Q high strength steel plate in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements.
