The main function of boron in A709 grade 36 bridge steel plate and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.
The cold working performance of A709 grade 36 bridge steel plate and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of A709 grade 36 bridge steel plate and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
Alloying agents like carbon and manganese along with steel lends a malleable nature to A572 structural high tensile steel plates, A709 grade 36 bridge steel plate, letting them be formed into various structurals that adapt quickly to constantly evolving needs of an edifice, thereby being flexible to changes. High tensile steel plates facilitate an increased load bearing capacity; their lighter bodies handle the extra weight without giving in to pressures. Heavy lifting and moving vehicles built from them increase weight bearing capacity, reduce time and labour cost to increase profits.
