The company Electrovek-Steel offers to purchase at a favorable price of the manufacturer rolling spring-spring steels of the right brands and profiles. The supplier guarantees the prompt delivery of products to the address specified by the customer.
Features of welding spring steel springs
The considered steels contain not less than 0.5… 0.75% carbon, and are often alloyed with other elements — chromium, vanadium, silicon. The most frequently used mode of heat treatment of such steels (quenching from 850… 880 о С in oil and subsequent tempering at 400… 640 о С) gives the steels the necessary strength and ductility parameters, but makes welding difficult. Therefore, the connection of spring-spring steels by the welding method can be successful only by pre-heating (annealing) the parts to be welded. After welding, it is necessary to re-heat the joint. It is recommended, if possible, to avoid welds in structures made of such steels.
Exception is spring-spring steel of mark 50ХГА, which is welded without restrictions, thus welding is made without heating, and without the subsequent thermal processing. At the same time, in this case, preheating to 200… 300 0 С is performed to obtain a long-lived joint, and then annealing is performed.
Buy in the range at competitive prices from the manufacturer of spring-steel steels of the required chemical composition and properties offers the company Electrovek-steel. The supplier ensures the timely delivery of products to any point specified by the customer.
Modes of welding products from spring-spring steels
If absolutely necessary, use electric welding at a maximum current of not less than 200 A, forming a suture cantle of the maximum possible dimensions: this ensures a satisfactory heating of the metal. In order to increase the efficiency of the welding process and reduce the consumption of welding electrodes, it is recommended to use a pulsed arc welding machine (for example, type Orion PA230). Good results are obtained by welding with electrodes made of austenitic stainless steel: in this case, the quality of welding increases due to the increased solubility of hydrogen in the melt and the increased plasticity of the metal.
The company Electrovek-Steel offers to purchase at affordable prices from the manufacturer of spring-spring steel of any assortment and brand. The supplier arranges prompt delivery of products to the address indicated by the consumer.
