What does the L in 316l mean?
Alloys often are added to steel to increase desired properties. Marine-grade stainless steel, called type 316, is resistant to certain types of corrosive environments. The “L” designation means 316L steel has less carbon than 316.
They can’t be strengthened by cold work to the identical degree as austenitic stainless steels. Austenitic stainless steel is the most important household of stainless steels, making up about two-thirds of all chrome steel production (see production figures under). They possess an austenitic microstructure, which is a face-centered cubic crystal construction.
The ease of welding largely is dependent upon the kind of chrome steel used. Austenitic stainless steels are the simplest to weld by electrical arc, with weld properties just like these of the base steel (not chilly-labored). Post-weld heat remedy is sort of at all times required while preheating earlier than welding can be needed in some cases.
Stainless steels have an extended history of utility in contact with water due to their glorious corrosion resistance. Applications embody a variety of conditions including plumbing, potable water and wastewater remedy, desalination, and brine remedy. Types 304 and 316 stainless steels are standard materials of construction involved with water.

Localized Corrosion
- Types 304 and 316 stainless steels are normal supplies of building in contact with water.
- Applications embrace a variety of situations together with plumbing, potable water and wastewater treatment, desalination, and brine remedy.
- Stainless steels have a long history of application in contact with water as a result of their glorious corrosion resistance.
- However, with increasing chloride contents, greater alloyed stainless steels such as Type 2205 and tremendous austenitic and super duplex stainless steels are used.
Our stainless production range
Thus, austenitic stainless steels usually are not hardenable by warmth remedy since they possess the identical microstructure at all temperatures. Grade 904L stainless-steel is a non-stabilized austenitic stainless-steel with low carbon content material.
Today, the oil and gas trade is the biggest consumer and has pushed for more corrosion resistant grades, leading to the development of super duplex and hyper duplex grades. Ferritic stainless steels possess a ferrite microstructure like carbon metal, which is a body-centered cubic crystal construction, and comprise between 10.5% and 27% chromium with very little or no nickel. This microstructure is current at all temperatures as a result of chromium addition, so they are not hardenable by heat treatment.
The corrosion resistance of grade 904L is intermediate between tremendous austenitic grades, with 6% molybdenum content material, and normal 316L austenitic grades. Grade 904L is less immune to nitric acid than grades 304L and 310L, that are free of molybdenum. This steel grade must be resolution treated following cold working, to attain maximum stress corrosion cracking resistance under critical environments. Grade 904L stainless steels have wonderful resistance to warm seawater and chloride attack. The high resistance of grade 904L towards stress corrosion cracking is as a result of presence of excessive amounts of nickel in its composition.
What are the different grade of stainless steel?
They are used for their good mechanical properties in the as-cast (and therefore as-welded condition) and/or their excellent corrosion resistance properties (particularly to stress corrosion cracking).
The properties of duplex stainless steels are achieved with an total lower alloy content material than similar-performing super-austenitic grades, making their use cost-effective for many applications. The pulp and paper business was one of many first to extensively use duplex chrome steel.
