Detailed Information:

We, at RatnaExporter.com, encourage excellence and novelty in our products and direct them into them through continuous efforts and quality control. We strive to provide our consumers with the highest quality product profile, so they can choose the right one for their business. We are an ISO 9001: 2015 company, committed to establishing and maintaining consumer-oriented business practices.

Manufacturer, trader, stockist, supplier, and exporter of A194 Gr. 4 Nuts that are permanently or temporarily fastened through clamping.

For pressure vessels, flanges, fittings and valves that operate at elevated pressures and temperatures, our ASTM A194 Gr. 4 Nuts are an essential component of the bolting material. Stainless Steel A194 Gr. 5 Flange Nuts attach corrosive media conveying pipelines. Carbon, Alloy, Martensitic, and Austenitic materials are covered by Stainless Steel A194 Gr. 4 Nuts.

A reliable collection of quality products has been built over the last 25 years. New, sustainable, and cost-effective products are continually developed in response to industry trends and demands.

You can choose from carbon, alloys, or martensitic stainless steel nuts in ASTM A194 specifications ranging in size from 1 1/4″ to 4 ” and from metric M6 to M100. As part of ASTM A194, austenitic stainless steel nuts are also covered in sizes ranging from 1 1/4″ to M6. The nuts are designed for high-pressure and high-temperature service, and grade substitutions are not permitted. Cold drawing or centerless grinding are two methods of further processing the material.

For high-temperature applications, ASTM A194 Grade 4 specifies an alloy steel molybdenum-chromium hexagon nut for use with Bolts or Stud Bolts ASTM A194 Grade B16. It is compatible with ASTM A194 Grade B4 bolts, providing high temperatures and corrosion resistance. It is occasionally determined to be the best stainless steel for high-pressure and high-temperature applications. Heat-treated and annealed at a minimum temperature of 1,050°F (565°C).

In contrast to standard hex nuts, ASTM A194 grade 4 heavy hex nuts are larger and thicker. They are designed to handle high-pressure and temperature applications on alloys, carbon steels, and stainless steels. The ASTM A194 Grade 4 Nuts have lower properties and yield strength as a result of absorption of heat at high temperatures. They are resistant to scaling at temperatures above 500°C. They are mechanical fasteners with threaded holes. To secure several parts together, it is always used in conjunction with a mating bolt that serves as a clamping force and stops axial movement.

The A194 gr 4 Square Nut is a four-sided nut with a greater surface in contact with the part it is fastened to, so it offers considerable resistance to loosening. It is intended for use at high temperatures. Because it provides good strength at this temperature and is especially resistant to short- and long-term exposure to combustion products and hot gases at temperatures higher than 500°C. A solid solution reinforced alloy steel, SA 194 gr 4 Finished Hex Nuts can be used over a certain temperature range. Because of this, its strength can usually be hardened by heat treatment, precipitation, and solid solution. In applications where increasing resistance temperature is critical, it combines a variety of alloying components for the purpose of attaining the desired properties.
