FAQ
-
How to choose different types of cast iron components? Which one suits my needs?
Prioritize matching based on usage scenarios: select ductile iron for applications requiring impact resistance and high strength (e.g., mechanical drive shafts); gray iron for cost-effectiveness and vibration damping (e.g., machine tool beds); malleable iron for pipe fittings and moderate toughness requirements (e.g., water pipe joints); and vermicular graphite iron for high-temperature working conditions (e.g., engine exhaust pipes).
-
Can the strength and hardness of cast iron components meet my usage requirements? How to verify?
Different types of cast iron components have clear performance standards. For example, ordinary gray iron has a tensile strength of ≥150MPa, and ductile iron can reach 400-800MPa. When purchasing, you can request material certificates, tensile test reports, and Brinell hardness test data from the supplier to ensure compliance with your operating load requirements.
-
Cast iron components are prone to rust. What anti-rust treatment solutions does the supplier offer?
Common anti-rust treatments include surface painting, galvanizing, chrome plating, or anti-rust oil coating; passivation treatment is available for special scenarios. When purchasing, confirm whether the supplier provides anti-rust treatment, as well as the weather resistance and service life of the anti-rust layer, to ensure it matches your storage or usage environment (e.g., outdoor, humid environments).
-
Can the supplier provide customized cast iron components? What is the minimum order quantity (MOQ)?Most cast iron manufacturers offer customization services, allowing adjustments to material, size, and structure based on your drawings. The MOQ varies by manufacturer: 10-50 units for standard products, 50-100 units for complex customized components, and some manufacturers support small-batch sampling (3-5 units) - confirm details in advance.
-
What is the service life of cast iron components? Will they crack easily under normal use?
Under normal operating conditions (complying with design loads, no overload/impact, and proper anti-rust measures), gray iron components have a service life of 5-10 years, and ductile iron components can last 10-20 years. As long as the selection is correct, installation is standardized, and sudden temperature changes and severe impacts are avoided, cracking rarely occurs.
-
If quality issues (e.g., cracks, dimensional discrepancies) are found after purchase, how to handle them?
Clarify after-sales guarantees when purchasing: quality inspection can be conducted within 7-15 days of receipt. For non-human-induced quality issues, replacement, return, or rework is supported. Some manufacturers offer a warranty period (e.g., 1 year), during which free repair or replacement is provided for quality-related problems - include this in the purchase contract.
-
How is the price of cast iron components calculated? Why is there a large price difference between different manufacturers?
Prices are mainly determined by material (ductile iron > vermicular graphite iron > malleable iron > gray iron), weight, processing complexity, surface treatment method, and order quantity. Significant price differences usually stem from variations in material purity (e.g., proportion of scrap steel), casting process (sand casting/precision casting), and inspection standards. Low-priced products may involve material adulteration or omission of key inspection steps.
