What is F316L?
F316L is an Austenitic Cr-Ni stainless steel. It is a low carbon derivative of F316 The Material is always supplied in the Solution Annealed condition. F316L is readily machinable in the annealed condition by milling， drilling， turning， etc as required.
What is ASTM A182?
ASTM A182 F6a is a forged martensitic stainless steel with 13 wt. Martensitic stainless steels can be high-carbon or low-carbon steel alloys. The ASTM standard A182 describes the general set of specifications about several material grades.

锻造
This alloy can be readily forged at temperatures 1000 – 1200Deg.C Hot working below 927Deg.C should be avoided. The low carbon content of these alloys ensures no heavy scale but excessive soak times should still be avoided to avoid enlarged grain size， suggest 15minutes per inch (25mm) of maximum ruling section.
热处理
This alloy is not hardenable by heat treatment and is therefore supplied in the Annealed condition. Anneal 1040Deg.C minimum， ensuring that sufficient time is allowed for the centre to achieve furnace temperature and hold for a time commensurate with the ruling section， followed by rapid cooling in Water.
机械加工
F316L is readily machinable in the annealed condition by milling， drilling， turning， etc as required. Cutting edges should be kept sharp and cuts should be kept light but deep enough to avoid work hardening. Coolants and lubricants should be used in large quantity.
耐腐蚀性
F316L has excellent corrosion resistance when exposed to a range of corrosive environments. It is usually regarded as Marine grade stainless， however it is not resistant to warm sea water. Warm Chloride environments can cause pitting and crevice corrosion. F316L will also suffer from stress corrosion cracking above 60Deg.C.
抗氧化性
This alloy has good resistance to oxidation in intermittent service upto 870Deg.C and in continuous service up to 925Deg.C. Whilst continuous use between 425 – 860Deg.C is not recommended for F316 if corrosion resistance in water is required this lower carbon variant， F316L， is recommended due to its resistance to carbide precipitation. When high strength at temperatures above 500Deg.C is required， grade F316H is recommended.
焊接
Austenitic stainless steels are generally considered to be weldable by the common fusion and resistance techniques but special consideration is required to avoid hot cracking of the weld metal. F316L was developed from standard F316 to be more amenable to welding and the lower carbon content increases the immunity to grain boundary carbide precipitation， making it suited to use in heavy gauge (>6mm) welded components.
