Advantages of Steel in Casting
Casting is a versatile metal processing technology with many variations. Any metal can find a suitable casting method, in which steel is the most commonly used material. Its advantages lie in 4 main points:
Rich Variants: There are many types of steels, and hundreds or even thousands of grades can be divided according to different classification criteria (composition, use, metallographic structure, etc.). Among these, over a hundred grades are specifically designed for casting to match different requirements.
Excellent Properties: Steel has excellent strength, toughness, ductility and wear resistance and is able to withstand high stress and impact loads. At the same time, steel has excellent weldability, which provides great flexibility for steel casting defect handling and application scenarios.
Best Strength-to-Cost Ratio: Cast iron accounts for about 70% of the global casting production, and steel only accounts for 15%, and the cost of cast steel is about 1.2 to 1.5 times that of cast iron, but the strength can easily reach more than twice that of cast iron.
Easy to Customize: Modern steelmaking technology can accurately control the carbon content, the proportion of alloying elements, and customize the properties of steel according to different uses.
Disadvantages of Steel in Casting
Of course, there are also some challenges in cast steel, which has lower fluidity than cast iron, high melting point and large shrinkage, which is more prone to casting defects such as shrinkage porosity and hot cracking. Overcoming these difficulties requires more demanding gating system designs and molds with better heat resistance.
FAQ
Find answers to common questions you may encounter before requesting a steel casting service quote from HDC.
Choosing the right steel for casting requires a systematic analysis of functional requirements, production constraints, and cost targets. HDC can help to choose the most suitable steel for your project based on your core requirements, help you evaluate manufacturing constraints, and give the most cost-effective option.
Yes, we can cast a max single piece under 5 tons by sand casting.
Yes, we can handle thin-wall casting with our advanced investment casting and die casting technology.
Of course, we source steel from reliable steel manufacturers, each batch has certifications, we can provide upon your request.
No specific MOQ, we need to discuss it based on the very order.
It varies from weeks to months. Prototypes and low volume production typically lead within 1-3 weeks, but high volume runs may take 2 - 4 months.
