What is the SPA-H maximum thickness BBN Steel advantages

In terms of service, our service is a "one-stop" way of working. We have our own SPA-H maximum thickness processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as SPA-H maximum thickness cutting, welding, drilling, galvanizing, etc., at the lowest cost.

ASME SA387Gr12CL2 steel plate chromium-molybdenum alloy steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen peeling, and sulfide corrosion in a hydrogen environment at medium temperature (350-480 ℃), and has good low temper brittleness. SPA-H maximum thickness, SA387 Gr12 CL2 steel plate is widely used in the manufacture of chemical fertilizer, petrochemical and thermal power plant equipment, such as synthetic ammonia reactor, coal gasifier, shift furnace and hydrogenation reactor.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. SPA-H maximum thickness, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

Alloying agents like carbon and manganese along with steel lends a malleable nature to A572 structural high tensile steel plates, SPA-H maximum thickness, 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.

What is the difference between Q345B steel and Q345A steel?
SPA-H maximum thickness, Q345B steel and Q345A steel have slight difference in chemical composition:
Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15;
Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15.
The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

We are professional SPA-H maximum thickness carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world. If you have any question about carbon steel materials, such as A36 steel modulus of elasticity, A283 grade C properties, A572 grade 50 hardness, SPA-H maximum thickness EN 10025 S235JR equivalent Indian standard, S355JR specification, carbon steel price etc., please feel free to consult us.
