Duplex Steel S31803 Hex Bolts

Duplex Stainless Steel S31803 Hex Bolts are a type of fastener made from a specific grade of duplex stainless steel known as S31803, which is also sometimes referred to as UNS S31803 or 2205 stainless steel. Here are some key features, information on corrosion resistance, applications, machining, and more:

Features:

• Duplex Stainless Steel: S31803 is a duplex stainless steel, which means it has a dual-phase microstructure consisting of both austenitic and ferritic phases. This combination of phases imparts several beneficial properties to the material.
• High Strength: Duplex stainless steels, including S31803, exhibit higher tensile and yield strengths compared to austenitic stainless steels like 304 and 316.
• Corrosion Resistance: Duplex stainless steel S31803 offers excellent corrosion resistance, particularly in environments containing chloride ions. This makes it suitable for use in aggressive and corrosive environments, such as those encountered in the chemical, petrochemical, and marine industries.
• Good Toughness: S31803 exhibits good toughness and ductility, making it suitable for various applications that require resistance to impact and shock loads.
• Weldability: While duplex stainless steels can be more challenging to weld than austenitic stainless steels, they are still weldable with appropriate techniques and filler materials.

Corrosion Resistance: Duplex stainless steel S31803 offers superior corrosion resistance compared to many other stainless steel grades. Its resistance to pitting and crevice corrosion is particularly noteworthy, making it suitable for use in seawater, acidic, and chloride-rich environments. It also has good resistance to stress corrosion cracking.

Applications: Duplex Stainless Steel S31803 Hex Bolts are used in various industries and applications, including:

• Oil and Gas Industry: S31803 hex bolts are commonly used in offshore platforms, subsea equipment, and pipelines due to their excellent corrosion resistance.
• Chemical Processing: They are employed in chemical plants, where resistance to corrosive chemicals and environments is critical.
• Marine Industry: Bolts made from S31803 are used in marine applications due to their resistance to seawater corrosion.
• Pulp and Paper Industry: They are suitable for use in pulp and paper processing equipment.
• Construction: In construction projects where corrosion resistance is essential, such as bridges and structures in coastal areas.

Specifications of Duplex Steel S31803 Hex Bolts

Machining: Machining duplex stainless steel, including S31803, can be more challenging than machining austenitic stainless steels due to its higher strength and work-hardening tendencies. Slower cutting speeds and appropriate tooling are often required to achieve good machining results. Lubrication and cooling are also important to prevent overheating and tool wear.
