The strength of A709 grade 50W bridge steel plate, 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing. Arc welding and contact welding have good welding performance and small thickness during gas welding. Cracks are likely to occur on parts with strict shape requirements or complex shapes.
Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate A709 grade 50W bridge steel plate should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.
The main applications of normalizing are as follows:① For low carbon steel, A709 grade 50W bridge steel plate. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
If you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time. Other than fresh production, we also have huge A709 grade 50W bridge steel plate stocks for the most widely used steel materials. So that the customers need not wait too long to get their required steel. Welcome to contact us and consult steel price, our sales person will give you professional answers and suggestions.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
