431 stainless bar, AISI 431 rounds and DIN 1.4057 steel rectangular bar with ULTRASONIC 100% OKIE test

Material certificates are a simple way to ensure you purchase dependable material aligned with your procuring needs. Manufacturers issue 2.2 certificates to confirm compliance with the order without showcasing test results. It guarantees that the items follow the required manufacturing standards. It does not allow you to evaluate a specific component, like an ASTM A276 type 431 square bar.

On the other hand, a 3.1 certificate applies only at the component level. Unlike a 2.2 certificate, it does not relate to the final product. Another significant difference is that this document shows the test results. Usually, a representative from the quality department of the manufacturer oversees it.

Grade 431 stainless steel comprises chromium (15-17%) and nickel (1.25-2.25%) with manganese, sulfur, silicon, phosphorus, and carbon. An AISI 431 flat bar displays brilliant corrosion resistance, toughness, and an admirable tensile strength of 850 to 1000Mpa.

The ASTM A276 standard requires manufacturers to adhere to strict tolerances for these bars. The standard H9 tolerance for round bars is +0mm to -0.052mm. It implies the acceptable product size should be 19.948mm to 20mm.

This metric indicates the allowed deviation in the dimensions during the manufacturing process. It may vary based on the shape (round, hex, square, and an ASTM A479 grade 431 rectangular bar). For example, hexagonal and square bars get covered by classes H11 and H12.

The standard dimensions of a stainless steel rectangular bar are 2000mm to 6000mm in length. The diameter can range from 3mm to 50mm. Most manufacturers can offer cut-to-size materials based on buyer specifications.

An AISI 431 round bar (UNS S43100 rounds) should undergo thorough testing to ensure the correct property profile for the customer. Most manufacturers use visual inspection and standard non-destructive tests like Eddy current, ultrasonic, and magnetic flux. These tests can detect defects and underlying concerns in the structure. Clients can also request destructive tests for an SS 431 cold drawn bar, like tensile deformation, flattening, leak tightness, and impact testing.

SS 431 bright bar and UNS S43100 square bars is available in a variety of diameters, grades and lengths

The A276 type 431 specification covers both cold-finished and hot-finished bars. DIN 1.4057 forged bars use Grade 431 stainless steel. Customers can order them in diverse shapes, such as square, hexagon, or a customised requirement.

The chosen method – hot or cold rolling – usually depends on the costs, budget, and client needs. Grade 431 steel cannot be cold-worked because of its high yield strength. The main difference lies in the processing temperature. Hot rolled steel goes over the recrystallisation temperature, while cold rolled steel stays under it. The latter produces smoother and strong bars without surface defects. However, it also has a higher internal stress that mandates stress relieving before delivering to the buyer.

Bright bars get produced through cold drawing, boasting a highly accurate molecular structure. Their perpetually bright surface finish gives them their name. Buyers can order SA 276 Gr 431 bright bars in straight or hexagonal shapes. Several industries – automobiles, machine components, and public construction – employ these bars as raw materials.

Hex bars have a hexagonal shape and are very common for fastening purposes. They get widely employed in nuts, bolts, etc., for their durability. The polygonal cross-section enables easy movement and alterations. The Brinell hardness of a SUS 431 hex bar ranges from 248 to 302.

Straight or rectangular bars don’t have as strict requirements for tolerance and size. However, they offer resistance to heat and impact. Typically, hex bars can be hard and rigid, suited to high-stress applications.
