Dual certified 304/304H is used as a material of construction up to 1500°F. Slight scaling begins at about 1200°F. This is the 0.04% minimum carbon version of type 304 stainless. 347 - Rolled Alloys, Inc.Both 347 and 321 offer good resistance to polythionic acid stress corrosion cracking, encountered in oil refineries. The high temperature oxidation resistance of 347 is similar to that of 304 stainless steel. Useful to 1500°F. Often in many product forms, the grain size and carbon content can meet both the 347S and 347H requirements.
Corrosion Resistance. Alloy 347 stainless steel plate exhibits good general corrosion resistance that is comparable to 304. It was developed for use in the chromium carbide precipitation range of 800 1500°F (427 816°C) where un-stabilized alloys such as 304 are subject to intergranular attack. Emissivity Coefficient Materials - Engineering ToolBoxThe emissivity coefficient - - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient = 1. The emissivity coefficient - - for some common materials can be found in the table below. Note that the emissivity coefficients for some products varies with the temperature.

Emissivity is a measure of a materials radiating efficiency. An emissivity of 1.00 implies that the material is 100% efficient at radiating energy. An emissivity of 0.20 implies that the material radiates only 20% of that which it is capable of radiating. Tables of emissivity values Emissivity of Specific Materials from Davis InstrumentsThe emissivity information below was determined under ideal conditions. Note:Surface contamination such as dust, oil films, or other agents will affect the actual emissivity of your material.

Tubing Alloy Information. The majority of stainless steel tubing and wire sold by Vita Needle Company falls in the 300 series stainless steel family. The composition of the stainless steel tubing varies depending on the alloy, but in general stainless can be an effective solution for many different types of Specification Sheet:Alloy 347/347H - Sandmeyer SteelAlloy 347 does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid. Fabrication Data Alloy 347 can be easily welded and processed by standard shop fabrication practices. Machining The cold work hardening rate of 321 makes it less machinable than 410 stainless steel, but similar to 304. Stainless Steel Alloy 347H - Continental Steel & Tube CompanyType 347H is a high carbon austenitic chromium stainless steel. Found in applications that demand high temperature resistance, other major design features include:Similar resistance and corrosion protection as Alloy 304 Used for heavy welded equipment when annealing is not possible Good oxidation resistance, on par with most other austenitic stainless steels Higher carbon allows
