SA 516 Gr.70 NACE / HIC / SSC Tested Plates, Sheets & Coils – Supplied by Global Brands

When it comes to oil, gas, and chemical industries, standard SA 516 Gr.70 is not enough.
Buyers need NACE MR0175, HIC, and SSC tested plates to prevent sulfide stress cracking (SSC), hydrogen-induced cracking (HIC), and brittle failure.

But here’s the buyer’s pain point:

  • “Local suppliers delivered Gr.70 plates, but they were not NACE compliant — our audit failed.”
  • “MTCs claimed HIC-tested, but no real test reports were available.”
  • “We faced penalties because the plates cracked during sour service inspection.”

At Navgraha Steels INC, Mumbai, we only supply genuine NACE-tested SA 516 Gr.70 plates, sheets & coils from reputed global mills:
Sail | AMNS | JSPL | Evonith | Nippon Yakin | Outokumpu | Special Metals | VDM | ATI

Every order is backed with:
NACE MR0175 compliance
HIC / SSC tested reports
Third-party inspections (SGS, BV, TÜV, Lloyd’s, DNV)
Mill traceability for zero rejection risk

Why NACE Tested SA 516 Gr.70 Is Critical

  1. Oil & Gas Pipelines → Prevent sulfide cracking in sour service.
  2. Refinery Vessels → Maintain toughness in H2S-rich environments
  3. Chemical Plants → Resist hydrogen damage in aggressive process fluids.
  4. Global Approvals → Pass EPC audits in GCC, Africa, SE Asia, EU, USA.

Without NACE / HIC compliance, projects face material rejection, safety risks, and shutdown delays

Buyer Pain Points (and Our Solution)

  • Wrong grade supplied → Material failed sour service test.
  • Delayed supply → Shutdown penalties & heavy losses.
  • Fake test certificates → Audit rejections & credibility loss.

With Navgraha Steels INC:

  • We guarantee authentic NACE / HIC certified supply.
  • Ready stock in Mumbai + imported lots for urgent projects.
  • Dual-stage inspection before dispatch.
  • Cut-to-size, slitted coils, export packing for global supply

Buyer Guide – Why Choose NACE / HIC Tested SA 516 Gr.70

Many EPC and refinery buyers face audit rejections because the plates were not genuinely NACE-compliant.
Here’s why NACE-tested material is essential:

  • Sour Service Safety → Prevents sulfide stress cracking (SSC) & hydrogen-induced cracking (HIC).
  • Mandatory for Oil & Gas → Refineries and offshore EPC contractors require NACE MR0175.
  • Global Acceptance → Ensures project approval in GCC, EU, USA, SE Asia.
  • Risk-Free Procurement → Avoids shutdown penalties and costly replacements.

For refinery shutdowns, oil storage tanks, and chemical vessels — SA 516 Gr.70 NACE is the only accepted choice.

Certifications, Approvals & Test Reports

Every NACE-compliant order is backed with:

  1. Mill Test Certificates (EN 10204 3.1 / 3.2)
  2. NACE MR0175, HIC, SSC test reports (as required)
  3. Third-party inspections – SGS, BV, TÜV, Lloyd’s, DNV
  4. ISO, ASME, PED approvals

This ensures full traceability and zero rejection risk in refinery & EPC audits
