Alloy Steel Stud Anchor Marine Ship Chain Mooring With CCS Certificate

Base Material Type:

Alloy steels used in marine environments typically utilize high-strength, seawater-resistant steels, such as certain high-strength low-alloy steels (AHSS/HSLA) or specific chromium-nickel-molybdenum alloy steels. Common grades include S355, S460, and even higher strength grades, depending on the load-bearing requirements and standard requirements.
Common Steel Grades and Material Standards (for reference when selecting materials):
Carbon Steel/Low-Alloy Steel: Common grades include high-strength steels in the AA, ASTM A/SA, and EN 10025 series.
Chromium-nickel-molybdenum alloy steels: Corrosion-resistant stainless steels such as 1.4404/316L are used in some structural sections, but high-strength carbon alloy steels are typically used for load-bearing components, with surface coatings used to enhance corrosion resistance.
High-strength low-alloy steels (HSLA): Examples include S355J2+N, S460N, and S690QL. Heat treatment and surface treatment are required to meet these requirements.

• Design and Heat Treatment:
  Heat treatment typically includes quenching and tempering (Q&T) to achieve the target yield strength (fy) and tensile strength (fu), while also controlling impact toughness to ensure fatigue life at the design temperature.
  Surface hardness targets and optional surface treatments such as carburizing/carbonitriding can enhance wear and pitting resistance.
  Protective Coatings and Corrosion Protection:
  Common coatings include galvanizing, epoxy coatings, polyethylene/polyurea topcoats, and powder coatings. Thickness is determined by the design environment (e.g., freshwater, seawater, or areas with acidic media).
  Cathodic protection may be required (e.g., incorporating a copper anode or external coating to reduce corrosion rates).
