UNS S44800 Stainless Steel Plate

S44800 stainless steel is a high nitrogen content austenitic stainless steel, also known as UNS S44800 or AISI 654SMO stainless steel. UNS S44800 Stainless Steel Plate has excellent corrosion resistance and strength, suitable for manufacturing high-demand chemical, marine and oil and gas fields parts and equipment, such as pipes, valves, storage tanks, heat exchangers, etc.

Standard: ASTM A240/A240M, ASTM A480/480M

Grade: UNS S44800

Density: 7.80 x 103 Kg/m³

Width: 1000mm, 1200mm, 1220mm, 1500mm, 1800mm, 2000mm, 2200mm

Length: 2438mm, 3000mm, 6000mm, 8000mm, 12000mm

Thickness: 0.3 - 50mm

The chemical composition of UNS S44800 Stainless Steel Plate is the key factor that determines its performance. Its main components include
Carbon (C): about 0.75%
Chromium (Cr): about 16.0% to 18.0%
Manganese (Mn): not more than 1.0%
Phosphorus (P): not more than 0.04%
Sulfur (S): not more than 0.03%
Silicon (Si): not more than 1.0%
Nickel (Ni): may contain trace amounts, but usually not more than 1%
Molybdenum (Mo): may contain trace amounts, but usually not more than 1%

The mechanical properties of UNS S44800 Stainless Steel Plate are as follows

Tensile strength: ob≥620 MPa

Yield strength: 00.2≥440 MPa

Elongation: 65>12%

Sectional reduction: ψ>40%

Hardness: HRC 52-58

S44800 can be improved by heat treatment. Common heat treatment processes include:
1. Quenching: Rapid heating in the temperature range of 1010-1070°C, followed by rapid cooling to form a martensitic structure.

2. Tempering: Tempering in the temperature range of 150-680°C to reduce internal stress after quenching, improve toughness and adjust hardness.

Processing performance

S44800 has good processing performance and can be processed by conventional metal processing methods such as milling, turning, drilling, etc. Due to its high hardness, carbide tools may be required during processing.

S44800 stainless steel is widely used in:

Manufacturing cutting tools such as scalpels, scissors, kitchen knives, etc.

Manufacturing corrosion-resistant parts such as bearings, pumps, valves, etc.

Manufacturing molds, mold accessories, mold steel, etc.

Manufacturing wear-resistant parts such as shafts, gears, wire drawing dies, etc.
