Frequently Asked Questions
Take a look and some of the most common questions. If you can not find the information you need, get in touch.
What types of precision stainless steel strips do we offer, and what are their common thickness and width ranges?
We provide precision stainless steel strips of various grades, such as 301, 304, and 316L. Thickness ranges from ultra - thin 0.01mm to several millimeters, and width varies from 2-300 millimeters to meet different customer requirements.
What is the difference between full - hard and half - hard stainless steel strips?
Full - hard stainless steel strips undergo special heat treatment to achieve maximum tensile and yield strength with minimal elongation, offering high strength but lower ductility. They are suitable for manufacturing components requiring high strength and dimensional stability, such as springs and fasteners.
Half - hard stainless steel strips balance strength and ductility. They maintain good strength while having moderate ductility, making them suitable for parts that require bending, forming, and stretching, such as electronic device brackets and automotive seat belt springs.
What are the main application fields of precision stainless steel strips?
Our precision stainless steel strips are widely used in multiple industries, including automotive (for manufacturing engine components, exhaust systems, etc.), electronics (for producing electronic connectors, springs, etc.), machinery manufacturing (for making various mechanical components), medical devices (for manufacturing surgical instruments, implants, etc.), and the chemical industry (for producing corrosion - resistant components like gaskets and reaction vessel linings).
Can precision stainless steel strips be customized, and what customized services do we offer?
Yes, we provide comprehensive customization services, including but not limited to dimensions (thickness, width, length), material grades, surface treatments (such as bright annealing, fingerprint - resistant treatment, etc.), and processing methods (cut - to - length, slitting, leveling, etc.), to meet customers' specific application requirements.
What is the dimensional accuracy of precision stainless steel strips, and how do we ensure it?
Our precision stainless steel strips have high dimensional accuracy, with thickness tolerance +/- 0.005 mm and width tolerances controlled within +/- 0.1 mm. We ensure this through advanced cold - rolling technology, high - precision measurement equipment, and strict quality control processes during production.
How does our company ensure the quality and stability of precision stainless steel strips?
We have a comprehensive quality management system covering raw material procurement, production processes, and product testing. Each batch of products undergoes rigorous inspections and tests, including dimensional measurements, mechanical property tests, and corrosion resistance evaluations, to ensure quality and stability.
What are the packaging forms for precision stainless steel strips, and how do we prevent damage during transportation?
Our precision stainless steel strips are packaged in various forms, such as coils and sheets. We use professional packaging materials and methods to prevent damage during transportation. For example, coils are wrapped with moisture - proof paper and secured with strapping bands, while sheets are stacked neatly and protected with corner guards to avoid edge damage.
What are your payment terms and conditions?
Our payment terms typically include a deposit upfront, with the balance payable upon completion and prior to shipping. Specific terms may vary depending on the order and can be discussed with our sales team.
What certifications do your products have?
Our products hold various certifications, such as ISO 9001:2015, RoHs, MSDS ensuring compliance with international standards and regulations.
What types of precision stainless steel products do you offer?
We mainly offer Austenitic 301, 304, and 316L precision stainless steel strips, slit coils, cut-to-length sheets and foils.
What is the minimum order quantity for precision stainless steel strips?
We strive to meet the needs of all customers. Although we encourage customers to purchase in bulk to enjoy more favorable prices and services, we also accommodate small - order requirements with MOQ of 100 kg. For specific minimum order quantities, please contact our sales team for detailed information.
How long is the delivery period for precision stainless steel strips?
We have an efficient production and supply chain management system and can deliver products quickly. The delivery period depends on the order quantity and product specifications. For regular products, we typically deliver within 7-10 working days. For customized products, the delivery period is negotiated with the customer based on specific requirements.
Do you provide product after - sales support and services?
Yes, we highly value customer satisfaction and provide comprehensive after - sales support and services. If customers encounter any quality issues or usage problems with our products, they can promptly contact our after - sales team. We will respond quickly and offer solutions, such as product replacement, repair, or technical guidance.
How should precision stainless steel strips be stored to ensure their quality during storage?
Precision stainless steel strips should be stored in a dry, ventilated warehouse, away from corrosive substances and environments. They should be placed on pallets to avoid direct contact with the ground and prevent moisture and contamination. Proper storage ensures product quality during storage.
