304l 1.4306

En 1.4306 / Aisi 304l

Core 304L/4306 is an austenitic chrome steel that belongs to the standard CrNi stainless steel family. Core 304L/4306 has the variant with 10.5 wt.% nickel for improved formability and low carbon content material for improved resistance towards intergranular corrosion after welding.

Core 304l/4306

It is price mentioning that steel loses its resistance to intergranular corrosion underneath the affect of chilly crushing and cold and hot bending of components. The hottest, fundamental and at the same time confirmed grade of chromium-nickel stainless-steel in the identified base combination 18/8 A240 304L Stainless steel plate, characterised by excellent intergranular, stress and pitting corrosion resistance. The 304 steel is characterized by full austenitic structure, low carbon content material, excellent impact strength, formability and ductility, glorious weldability, non-magnetic properties and susceptibility to bending and machining.

  • China Supplier, Manufacturer and exporter of austenitic, nickel alloy material, duplex steel, stainless-steel pipe, tube, tubing, seamless stainless steel pipe, welded chrome steel pipe, pipe fitting.
  • Otherwise, the improved model of grade 1.4307 / AISI 304L. Used where regular 304 or 304L materials isn’t enough and increased corrosion resistance is required.
  • Acid resistant stainless steel with the addition of nitrogen, decreased carbon content and elevated chromium 18-20% and nickel 10-12%.


Over time, years of expertise and practice, many types of modified 304 steel have been developed, with restricted carbon content and even elevated or decreased content material of nickel, chromium, sulphur and phosphorus, similar to 1.4305, 1.4306, 1.4307 and 1.4310. As a basic, well-liked and versatile stainless-steel material, its use must be classified as basic. In more aggressive environments, the chemical composition is unfortunately not sufficient, which leads manufacturers to make use of “top shelf” materials containing Molybdenum and Titanium – corresponding to 316L, 316Ti.

X8crnis18-9, 1.4305, Aisi 303 – Automatic Stainless Steel With High Carbon And Sulphur Content For Cutting.

China Supplier, Manufacturer and exporter of austenitic, nickel alloy material, duplex steel, chrome steel pipe, tube, tubing, seamless stainless steel pipe, welded stainless-steel pipe, pipe becoming. Acid resistant stainless-steel with the addition of nitrogen, lowered carbon content and increased chromium 18-20% and nickel 10-12%. Otherwise, the improved version of grade 1.4307 / AISI 304L. Used the place regular 304 or 304L material isn’t adequate and elevated corrosion resistance is required.

Attention should also be paid to the high sprucing energy of the material and susceptibility to crushing, mainly within the case of chrome steel tapes, which after curing attain a energy of N/mm2. If greater strength is required, larger carbon metal 1.4310 / AISI 301 is used. In addition, the 18/8 Cr-Ni grades are prone to mechanical sawing, water cutting and all types of thermal slicing (plasma and laser). X5CrNi18-10 and S30400 metal is a mass-produced grade, appearing in most types of semi-completed products, ranging from pipes, sheets, bars, profiles or strips. Core 304L/4306 is the next nickel different to Core 304L/4307 with improved formability and deep drawability.
