Import Heat Resiotance Steel(Hh) — Buy in wholesale FOB from Supplier in India

Heat Resiotance Steel(HH) is a chromium‑nickel alloy steel formulated to retain mechanical strength at temperatures approaching 1000 °C. The material is described as an industrial‑grade steel that resists oxidation and maintains dimensional stability in furnace and petro‑chemical environments. It is supplied in plate, sheet and structural forms, allowing flexibility for a range of component designs. The alloy complies with ASTM A297 specifications, a common standard for high‑temperature steel products.

Typical HH‑grade steel contains 8 - 10 % chromium and 2 - 4 % nickel, with carbon limited to a maximum of 0.2 %; these composition ranges are standard for heat‑resistant alloys used worldwide. Tensile strength values around 550 MPa and yield strength near 350 MPa are typical for this grade, providing the necessary load‑bearing capacity at elevated temperatures. The steel’s hardness is usually about 190 HB, and its density is approximately 7.85 g cm‑3, matching conventional carbon‑based alloys. Standard testing according to ASTM A297 includes a heat‑affected zone assessment and high‑temperature tensile testing.

End users such as furnace manufacturers, heat‑treatment equipment makers and petro‑chemical plant engineers select this steel for components like burner liners, refractory supports and high‑temperature structural frames. While the listing mentions flexible minimum order quantities, the exact MOQ, lead time and payment conditions must be clarified directly with Sri Steel Industries. Shipping can be arranged under common incoterms and the supplier can provide export documentation once the order is confirmed. Prospective buyers are encouraged to request a mill test certificate and, if needed, a sample to verify alloy composition before committing to volume purchases.

Sri Steel Industries is located at 138/2, Chikkarampalayam, Karamadai, Coimbatore 641104, Tamil Nadu, India. The company is classified as a harbor‑trust tier supplier, indicating that its export activities have been verified through customs records. Its platform response rate is shown as 0 %, and no average response time is recorded, so buyers should allow additional time for communication. Sri Steel Industries focuses on manufacturing heat‑resistant alloy steels and offers the HH‑grade product in multiple forms.

The profile does not list production capacity, ISO certifications or specific quality‑management systems, therefore purchasers should request copies of any relevant mill test certificates and quality audit reports. As an exporter, the firm can arrange freight under standard incoterms such as FOB or CIF from Indian ports, and it accepts common payment methods like L/C and T/T after order confirmation. Packaging details are not specified; buyers need to confirm whether the steel will be shipped in pallets, bundles or bulk containers.
