304l 1.4307

Spec: En 10088-three:2005

Stainless metal by-product from 1.4301 with lowered carbon content material, increased chromium and nickel. Paul Meijering delivers pipes, fittings, flanges and sheets in stainless-steel and particular alloys immediately from stock. Apart from a variety of high-high quality materials, we provide customised solutions and particular processing. Marcel Saas is certainly one of our consultants in the area of all types of stainless-steel, however is also a fan of our primary chrome steel 304L. He is aware of all in regards to the many purposes for which 304L is imminently suitable, and would love to assist you further.


Pitting and crevice corrosion can happen in environments containing chlorides. This additionally applies to certain liquid metals at high temperatures – lead, cadmium, zinc, and alumina.

  • AISI 304, 1.4301, X5CrNi18-10 grade spinoff appropriate for machining, categorised as stainless automatic metal with increased concentration of Sulphur and Coal.
  • Steel with slightly worse corrosion resistance than AISI 304 / 1.4301 because of comparatively high carbon content.
  • The function of the change is to facilitate machining, improve chip brittleness because of the launch of Sulphides during the process.
  • It is distinguished from the basic grade by its lack of resistance to intergranular corrosion in supply and sensitized condition.

Corrosion Resistance

If you have any questions about 304L stainless steel, our specialists would be joyful to help. Stainless steel 304L (UNS S30403) is the most broadly used ‘18-eight’ chromium-nickel austenitic chrome steel.

Commercially produced steels, utilizing present steelmaking strategies, are often produced because the low carbon kind as a matter in fact due to the improved management in trendy steelmaking. Consequently completed steel merchandise are often provided to the market ‘dual licensed’ to both grade designations as they will then be used for fabrications specifying either grade, inside a selected normal. The welding consumables for both varieties are primarily based on a low carbon composition, to avoid intercrystalline corrosion danger within the solidified weld nugget or from the diffusion of carbon into the father or mother (surrounding) metallic. If the carbon degree is under zero.030% then this intercrystalline corrosion doesn’t take place following publicity to these temperatures, particularly for the kind of instances normally skilled in the warmth affected zone of welds in ‘thick’ sections of steel.

There are two European steels of the ‘304L’ type, 1.4306 and 1.4307. The 1.4307 is the variant most commonly A240 304L Stainless steel plate offered, outside Germany.
