Obtaining the proper certifications for both our foundry and the people working in it serve to earn that trust. Maintaining those certifications underscores our commitment to quality.

Company Certifications

Member of Nebraska Safety Council

We strive toward creating the safest environment possible for employees, visitors, and our community. Our Nebraska Safety Council membership shows our commitment to that end. Our people are Omaha Steel’s greatest asset, and our commitment starts with ensuring their safety.


ISO 9001

Omaha Steel meets the steel industry standard of ISO 9001 certification. The ISO 9001 standard is recognized internationally, and the management system applies to the manufacture of steel and alloy-steel castings. ISO 9001 includes compliance with EU Pressure Equipment Directive, Annex I, Paragraph 4.3.

ISO 9001 Certificate


Pressure Equipment Directive/PED-Welding

Omaha Steel offers compliance with the Pressure Equipment Directive in both casting and welding processes. Created for the European Union, this directive sets standards of design and fabrication of castings used in the manufacture and finishing of pressure equipment. Items falling under the PED designation of pressure equipment include safety valves, pipes, and steam boilers. Omaha Steel also has PED welding accreditation, determined by an independent entity, for ASTM A216 WCB/SA-216 WCB and ASTM CF8M/SA-351 CF8M alloys.


American Society of Mechanical Engineers (ASME)

Omaha Steel offers compliance with codes created and administered by the American Society of Mechanical Engineers (ASME). This professional association created standards for a wide variety of engineering standards across many industries. Founded in 1880, the ASME today has a global reach, and its mission toward engineering excellence spans many industries and disciplines.


American Iron and Steel (AIS)

Domestic projects involving the transmission and storage of water, especially regarding clean/drinking water, may be subject to AIS (American Iron and Steel) compliance, either partially or in full, as required by the EPA. Omaha Steel meets the requirements of AIS.

Employee Certifications

The American Society for Non-Destructive Testing (ASNT)

ASNT (American Society for Nondestructive Testing) certification, recognized throughout the steel industry as the standard for NDT, assures you that all NDT done by Omaha Steel employees meets ASNT criteria. ASNT certification means that the specific Omaha Steel employee administering NDT has exhibited competence as validated by an impartial panel.

American Society for Testing and Materials (ASTM) A488

ASTM (American Society for Testing and Materials) works internationally, and has created over 12,000 standards across every single industry. The A488 certification relates to the procedural and personnel qualification of steel casting fabrication and repair through electric arc welding across a variety of steels and alloys. A488 includes four types of tests: tension test, bend test, Charpy impact testing, and radiographic testing. Procedures and personnel meeting ASME Section IX are automatically qualified for ASTM A488. Omaha Steel has qualified procedures and personnel meeting ASTM A488.

Non-Destructive Testing (NDT)

Non-destructive testing (NDT) requires visual inspection, and those doing such inspection must pass certification. Omaha Steel visual inspection associates have earned visual inspection for NDT.

National Aerospace Standard (NAS) 410

Steel foundries such as Omaha Steel that serve military, defense, and aerospace clients must have a NAS 410-certified NDT employee on staff. The NAS 410 (National Aerospace Standard) certification replaced the MIL-STD-410 standard. Omaha Steel has staff that meets NAS 410, covering visual, magnetic particle, and liquid penetrant inspection.


SNT-TC-1A, developed by the American Society for Nondestructive Testing, provides us guidelines for certification of NDT examination. ASNT sets up these guidelines for foundries and manufacturers wanting an in-house NDT certification program for their employees. This certification program offers three levels: I, II, and III. Omaha Steel offers Level II on-site, and we have ready access to Level III should you require it. ASNT updates these guidelines annually. Omaha Steel performs nondestructive testing that’s written to and compliant with SNT-TC-1A, covering visual, magnetic particle, and liquid penetrant inspection.

NACE MR0175, NACE MR0103

These two standards are issued by NACE International. NACE International serves the foundry industry by providing authoritative standards, certification, and technical training for corrosion control. The NACE MR0175 standard is federally mandated and is known internationally as ISO 15156. MR0175 provides the requirements for selection and qualification of materials used for H2S in the oil and gas industry. MR0103 (ISO 17495) is a relatively new NACE standard and specifically relates to petroleum refineries. Both standards cover appropriate materials and mechanical properties for best inhibiting sulfide stress cracking. Some requirements of MR0103 are more stringent than MR0175. Omaha Steel can design and cast parts that meet one or both standards.


Steel Founders’ Society of America (SFSA)

Omaha Steel is a proud member of Steel Founders’ Society of America. This organization, founded in 1902, helps guide the steel industry in both America and overseas. It pushes toward new developments and technological advancement in the steel industry, promotes market development, assists with specification and regulation development, and provides member foundries with business information and advanced training.

Valve Manufacturers Association of America (VMA)

Membership in the Valve Manufacturers Association of America requires that member companies have a significant interest in the manufacture, distribution, and sales of valves, actuators, and controls. Omaha Steel has long served the valve market with a wide array of steel castings. VMA, based in Washington, D.C., serves the interests of member North American companies through meetings, seminars, and publications focusing on industry business development, management, technology, government and trade issues, and education.
