Stainless Steel Plates for the Steel Rolling and Forging Industry: 310S/304 Selection and 6 Part Lists
In the steel rolling and forging industry, we have compiled six parts that use stainless steel: commonly used 310S / 304 / 904L, with thickness ranging from 3–275 mm.
6 parts and selection list

Table isStandard Configuration.Same part can use 304, 316L, or 2205 depending on media, temperature, and welding method—explain the conditions clearly, it's easier than specifying grades.
Material essentials
- Top 3 grades in this industry are 310S (3), 304 (2), and 904L (2). —— numbers in parentheses indicate the number of affected areas, useful for quoting and material planning.
- For high-temperature sections, consider 310S / heat-resistant castings.
- Chlorides and salts are the most common corrosive sources (pitting, crevice corrosion).
- Thickness range: 3–275 mm —— thin plates are typically formed parts (consider bending rebound and deep drawing cracking), thick plates are usually welded structures (consider heat input and sensitization).
Common Issues
Which stainless steel is used most in the black metal smelting and rolling industry?
Based on total pages, the top 3 areas are 310S (3), 304 (2), and 904L (2). Specific parts still depend on media and temperature, e.g., a stainless countertop that contacts salt water should switch from 304 to 316L.
Which part is the easiest to go wrong?
Failure description, typical example is "Continuous caster foot rolls": thermal fatigue (surface-to-core temperature difference around 300℃ → networked thermal cracks) + acidic corrosion (protective slag + cooling water) + wear; weld joint/axle hole deforms after 3 heats; recommended grade 1Cr13 high Ni stainless steel overlay/Ni-based overlay; base material 42CrMo, specifications roll diameter φ100–275mm. This type of condition recommends specifying medium concentration, temperature, and cleaning method in the design phase.
What thickness should I select?
Thickness range in the list is 3–275 mm. For thin sections, consider bending and surface finish; for thick sections, welding and structural strength. Values may vary by manufacturer for the same location, review your drawing or operating conditions.
