Spring Carbon Steel Rod is a steel bar specifically used to manufacture various types of springs, such as coil springs, leaf springs, and disc springs. Its core requirements are excellent elasticity, high fatigue strength, and sufficient toughness to ensure that the spring can operate stably under long-term alternating loads without permanent deformation or fracture.
Carbon steel refers to steel materials with a carbon content between 0.05% and 2.11%. In carbon steel, the higher the content of carbon elements, the greater the hardness, the higher the strength, hot rolled steel bars are divided into low carbon steel, medium carbon steel and high carbon steel and other different grades and specifications. Among them, low carbon steel rods (such as Q235B) are widely used in building structures, Bridges, ships and other fields; Medium carbon steel rod (such as 45# steel) is suitable for mechanical parts, bearings, etc. High carbon steel rods (such as 55# steel) are used to make parts with higher strength requirements, such as springs.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
