CF8M Stainless Steel
CF8M is a grade of stainless steel castings in ASTM A351, which has chemical composition and properties equivalent to 316 stainless steel (forgings or profiles) instead of 316L. Here is a detailed analysis:
Material correspondence
The chemical composition and corrosion resistance of CF8M and 316 are similar, but their forms are different: CF8M specifically refers to castings, while 316 covers pipes, bars, forgings, etc.
Multiple sources clearly indicate that CF8M corresponds to 316, while CF3M corresponds to 316L. For example:
CF8M = 316 (ZG0Cr17Ni12Mo2)
CF3M = 316L (ZG00Cr17Ni14Mo2)
Difference between standards and uses
The execution standard of CF8M is ASTM A351 and it is used for casting pressure-bearing components such as valve bodies and pump bodies. The execution standard of 316 is ASTM A959 and it is applicable for processing into a variety of industrial products.
316L (low-carbon version) is achieved in casting form through CF3M. Both have a lower carbon content and are more suitable for welding and intergranular corrosion resistance scenarios.
Mechanical property comparison
316 forgings usually have better mechanical properties (such as strength and ductility) than CF8M castings, but the actual gap is relatively small. The casting process may cause defects such as pores in the castings, which need to be improved through heat treatment.
All of our products are custom made according to clients' drawings. Our work flow chart is as belows:
Precisely match demands and eliminate compromise
Non-standard Adaptation : Produced directly according to the drawings, it perfectly meets the special requirements of equipment interfaces, installation space, etc., avoiding the adaptation risks of market standard parts being "forced to fit the shoes".
Function Integration : Complex structures (such as internal flow channels, multi-hole positions) are integrally cast, eliminating the need for welding/assembly steps, reducing leakage risks, and enhancing structural strength.
Cost reduction and efficiency improvement, with significant long-term value
Zero inventory pressure : Customized on demand to avoid inventory overstock and capital occupation caused by bulk purchase of standard parts.
Process economy : The material utilization rate of precision casting is over 90%, reducing machining waste. The cost per piece is more than 30% lower than that of secondary modified standard parts.
Quality is controllable and risks are approaching zero
Full Traceability : Strictly follow the specifications from materials to processes (investment casting), and provide material reports and flaw detection tests.
Tolerance Guarantee : The combined process of precision casting and machining ensures a key dimensional tolerance of ±0.05mm, guaranteeing assembly reliability.
Respond quickly and seize the initiative
Flexible Iteration : Supports rapid optimization of drawings (such as wall thickness adjustment, addition or reduction of reinforcing ribs), accelerating product upgrades.
Small-batch friendly : minimum order quantity is 50 pieces, and the delivery cycle is 40% shorter than that of "modified standard parts" purchased from the market.
Customized according to drawings breaks through the limitations of standard parts with precision, economy and reliability , especially suitable for heavy industry, automation, high-end equipment and other fields, helping you achieve "Special parts for special purposes, efficiency doubled" !
1Q: How is the compatibility of non-standard parts? What if it can't be assembled?
1A: Assembly is worry-free. Actual measurement is the standard! The first full-size inspection report is provided with the goods and supports third-party re-inspection. Emergency issues are responded to within 48 hours. Repair or rework is supported (free of charge after responsibility is defined).
2Q: Will repeated modifications of design drawings affect the delivery cycle?
2A: 24-hour response, free drawing optimization! The engineering team conducts synchronous reviews and provides quick feedback on manufacturability suggestions (such as wall thickness and fillet).
3Q: Can long-term cooperation ensure the stability of production capacity and prices?
3A: Double insurance commitment for the supply chain!
Raw material reserves: Strategic cooperative steel mills, with regular inventory of stainless steel/low-carbon steel.
Capacity guarantee: We have our own casting and machining production lines with a monthly capacity of 300,000 pieces. Urgent orders for power strips will be given priority.
Price lock-up: The annual framework agreement offers a 12-month price freeze, eliminating the risk of fluctuations in antigen materials.
4Q: How long will you take to quote a non-standard casting parts?
4A: 3 days.
5Q: Do you have better payment term?
5A: Yes, of course. This could be negotiated after we start cooperation.
