We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
In some functions, these grades can be utilized as a replacement for austenitic chrome steel grade 304. Welding of grade 904L stainless steels may be carried out using all typical strategies. This grade does not require pre-warmth and submit-weld heat remedies. Grade 904L may be subjected to hot cracking in constrained weldment. Grade 904L electrodes and rods are used for welding grade 904L steels in accordance with AS 1554.6.
Nowadays, most brands make the most of 316L stainless steel. Unlike the rest of the industry, Rolex makes use of 904L stainless steel for qualities that Rolex believes surpasses the industry commonplace. The weak point of conventional stainless steels is their limited resistance to crevice corrosion. In seawater, for example, there’s a significantly higher risk of crevice corrosion underneath gaskets, deposits or fouling.
Ferritic stainless-steel alloys can usually be categorized into five groups, three households of ordinary grades (Groups 1 to 3) and two households of specialty grade steels (Groups four and 5). While commonplace ferritic steels are, by far, the biggest client group in terms of tonnage, demand for specialty grade stainless steels is increasing steadily.
Our stainless production range
- Grade 904L stainless steels have excellent resistance to warm seawater and chloride assault.
- The excessive resistance of grade 904L towards stress corrosion cracking is as a result of presence of excessive amounts of nickel in its composition.
- Grade 444, specifically, has a pitting resistance equal (PRE) that is similar to grade 316 austenitic chrome steel, allowing it to be used in additional corrosive out of doors environments.
Applications For 304 Stainless Steel
The result’s steel with wonderful corrosion and scaling (or oxidation) resistance. In truth, the corrosion resistance of grade 447 is equal to that of titanium steel. Group 5 steels are sometimes utilized in extremely corrosive coastal and offshore environments. The two steel grades are comparable in look, chemical makeup and characteristics.
Although subsequent annealing just isn’t required in most cases, it must be carried out when the fabrication is performed under severe stress corrosion cracking circumstances. Grade 904L stainless-steel is a non-stabilized austenitic stainless steel with low carbon content. This excessive alloy stainless-steel is added with copper to improve its resistance to strong reducing acids, similar to sulphuric acid. The steel can also be proof against stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers wonderful formability, toughness and weldability.
What are the different grade of stainless steel?
Rolex calls 904L stainless steel a “corrosion-resistant superalloy.” 904L differs from 316L because of extra Chromium, Molybdenum, Nickel, and Copper that gives it improved resistance to acids.
In comparability to austenitic stainless steels, which have a face-centered cubic (FCC) grain construction, ferritic steels are defined by a body-centered cubic (BCC) grain structure. In other words, the crystal structure of such steels is comprised of a cubic atom cell with an atom within the center. The most simple difference between the grades of steel is the presence of molybdenum in stainless 316. Molybdenum is a chemical element used for the strengthening and hardening of metal.

What is the difference between 304 and 316l 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 mostly used ferritic steels are found in Group 2. They have a better chromium content material and are, consequently, more resistant to corrosion by nitric acids, sulfur gases, and lots of natural and food acids.
