Premium-Grade Stainless Steel 90 Degree Elbow | Custom Sizing

Premium-Grade Stainless Steel 90 Degree Elbow | Custom Sizing

Product Overview

Our stainless steel elbow 1 2 is engineered for superior performance in industrial, sanitary, and high-pressure environments. Designed to meet global standards (ASME B16.9, DIN 2605, JIS), this 90-degree elbow ensures seamless directional changes in pipelines while offering unmatched corrosion resistance and durability.

Technical Specifications

Key Properties

1. Tensile & Yield Strength

• Tensile Strength: 515–1050 MPa (varies with grade and heat treatment).
  • Cold-worked 304 achieves up to 1050 MPa for high-stress applications.
• Yield Strength: 205–310 MPa (304/316L), ensuring structural integrity under pressure.

2. Bend Strength

• Withstands deformation even at extreme angles due to austenitic microstructure.
• Impact Strength: 0.0118–0.0143 J/mm³ (316L excels in corrosive environments).

Identification & Marking

• Laser Etching: Permanent markings include material grade (e.g., SS304), size, thickness, and certification codes (ASME B16.9).
• Color Coding: Optional silver or epoxy-coated ends for easy pipeline identification.

Weight Calculation

Use the formula for stainless steel elbow catch precision:
$W=0.387\times S\times (D-S)\times R/1000$

• W: Weight (kg)
• S: Wall Thickness (mm)
• D: Outer Diameter (mm)
• R: Bend Radius (1D or 1.5D)

Example:
For a 2″ (DN50) SCH40 elbow (D=60.3mm, S=3.9mm, R=1.5D):
$W=0.387\times 3.9\times (60.3-3.9)\times 90.45/1000\approx 0.76\text{kg}$

Why Stainless Steel Elbows Rust?

While stainless steel is corrosion-resistant, improper handling or environmental factors can cause localized rust:

1. Passive Layer Damage: Scratches or abrasive cleaning disrupt the chromium oxide layer, exposing iron to oxidation.
2. Electrochemical Corrosion: Contact with carbon steel debris in humid conditions creates galvanic cells.
3. Chloride Exposure: Coastal or chemical environments accelerate pitting corrosion in 304/316 grades.
4. Organic Residues: Food or organic acids (e.g., citric acid) degrade the surface if not cleaned promptly.
5. High-Temperature Scaling: Prolonged exposure >400°C oxidizes chromium, reducing corrosion resistance.

Why Choose Our Stainless Steel Elbows?

1. Certified Quality: Third-party audited (SGS, ISO 9001) with full traceability.
2. Custom Sizing: Tailored stainless steel elbow dimensions and thickness for unique applications.
3. Hygienic Design: Mirror-polished surfaces (Ra ≤0.8μm) prevent bacterial growth in food/pharma industries.
4. Global Compliance: Meets ASME, DIN, JIS, and 3A standards for cross-industry compatibility.
5. Lifetime Warranty: Rigorous hydrostatic and radiographic testing ensures zero defects.
