Angle bracket | A2 | M8341

If you are looking for an angle bracket that can handle direct fastening, anchoring, or suspension in demanding environments without rusting, the A2 stainless steel angle bracket is a reliable choice. It is manufactured from A2 stainless steel according to material class A2-70 and designed to withstand moisture, chemicals, salt, and fluctuating temperatures – properties that make it particularly suitable for outdoor use, industrial environments, and marine applications.

APPLICATION AREA

The A2 stainless steel angle bracket is intended for precise and stable mounting of, for example, wood or steel structures in environments such as coastal areas, wet rooms, the food industry, or chemical plants. With its pre-drilled holes, it allows for easy installation when fastening to wood, concrete, or brick, often in combination with stainless steel screws or bolts. The stainless steel surface minimizes the need for maintenance and ensures that the structure lasts for many years, even under high moisture exposure. It is easily installed using a screwdriver or socket tool, depending on the choice of fastener.

FREQUENTLY ASKED QUESTIONS (FAQ)

What does the A2-70 material class mean for an angle bracket?

The designation A2-70 specifies both the steel material's corrosion class and its mechanical strength:

• A2 (AISI 304 / 1.4301): Stainless steel that provides excellent resistance to moisture, outdoor climates, fresh and rainwater, and mild chemicals.

• 70 (Tensile strength): Indicates a minimum tensile strength of $700\text{ MPa}$ ($700\text{ N/mm}^2$). This guarantees high torsional and bending strength for structural fastenings, suspensions, and framework construction.

Why are A2 steel angle brackets suitable for outdoor frames and suspensions?

When angle brackets are used as load-bearing corner connections or mounting brackets outdoors, moisture, dirt, and rainwater often collect in the corners. A galvanized angle bracket risks rusting through at cut edges and screw holes over time. A2 stainless steel forms a self-healing chromium oxide passive layer that protects the entire component against corrosion and maintains its mechanical load-bearing capacity throughout its service life.

What should be kept in mind when choosing fasteners and installing stainless steel angle brackets?

• Avoid galvanic corrosion: Always use stainless steel screws, bolts, and washers (at least stainless A2 or acid-proof A4) during installation. Bolts made of galvanized or untreated steel cause galvanic corrosion, which is accelerated in humid environments.

• Precision in drilling: If you need to drill additional holes in the angle bracket, use sharp cobalt-alloyed high-speed steel (HSS-Co) or carbide drill bits and run at low speed with cutting oil to prevent the steel from work-hardening.
