Practical Selection Tips

1. Core Screening Factors

For petrochemical scenarios: Prioritize plates with API 5L certification, yield strength ≥205MPa, and corrosion resistance rating ≥9.0 in salt spray tests. Refer to the API Specification 5L for standard compliance verification.

For steel structure processing: Focus on dimensional tolerance ≤±0.1mm, flatness error ≤0.5mm/m, and value-added processing capabilities such as precision cutting. Consult the GB/T 3280-2015 standard for quality reference.

For mechanical manufacturing: Select plates with hardness HB180-HB220, tensile strength ≥515MPa, and SGS or BV third-party certification. Refer to the ASTM A240 standard for mechanical performance requirements.

2. Common Pitfall Avoidance

Avoid choosing products solely based on price; low-cost plates often have inconsistent chemical composition, leading to performance failures. Verify MTC certification documents before purchasing to ensure material compliance.

For customized orders, confirm the manufacturer’s processing precision and delivery cycle in advance. Avoid suppliers with vague lead time commitments, as delayed delivery can disrupt project schedules.

3. Quick Decision Method

Create a scoring table based on certification compliance, mechanical performance, processing capabilities, and user feedback. Assign weights of 30%, 25%, 25%, and 20% respectively, and calculate the total score to compare brands objectively.
