KSLOK Stainless Steel 316 tube fittings is fully intercheangable with Swagelok & Alok fittings.
Stainless Steel 316 tube fittings have a huge variety of application in the instrumentation and caliberation industry. Bulk of the requirement and consumption is in the oil and gas , Hydraulics , Pneumatics & Research and Development sectors.
BACKGROUND
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.
The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.
PRODUCT RANGE AT KSC
The product range for instrumentation includes tube fitting, valves, pipe fittings, manifolds, condensate pots.With a state-of-the-art inhouse automated machinery , we believe in the concept of Fit-&-Forget. The Fittings have strong endurance and durability , with precision in Threading ( NPT, BSPT , BSPP) . Each and every individual unit is tested for gauge and pressure before it leaves the premises. Thus we have not faced a single rejection in exports of our tube fitting in the last decade.Production Capacity : 25000 units per month.
KEY PROPERTIES
These properties are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.
Corrosion Resistance
Excellent in a range of atmospheric environments and many corrosive media – generally more resistant than 304. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C. Considered resistant to potable water with up to about 1000mg/L chlorides at ambient temperatures, reducing to about 500mg/L at 60°C.
316 is usually regarded as the standard “marine grade stainless steel”, but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish.
Heat Treatment
Solution Treatment (Annealing) – Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment.
Machining
316L stainless steel tends to work harden if machined too quickly. For this reason low speeds and constant feed rates are recommended.
316L stainless steel is also easier to machine compared to 316 stainless steel due its lower carbon content.
