What is the difference between RNS 310 and RNS 315?
RNS310 is an older version head unit with a lower quality screen, while the RNS315 is better screen and much newer. The differences are internal as both look pretty much the same, but they’re very different beasts overall (once you get past the visual side of things). Both are double-DIN-sized head units and have a 6. The more expensive RNS510, though, features a higher resolution display — 800×480 compared to the RCD510’s 400×240 — as well as a television-esque 16:9 width-to-height screen ratio.
What is the difference between 310 and 310S?
Grade 310 is a medium carbon austenitic stainless steel, for high temperature applications such as furnace parts and heat treatment equipment. It is used at temperatures up to 1150°C in continuous service, and 1035°C in intermittent service. Grade 310S is a low carbon version of grade 310. This grade is written as 1. X8CrNi25-21 according to EN norm and it is written as UNS S31008 according to UNS norm.This grade is also very ductile, and has good weldability enabling its widespread usage in many applications. S find wide application in all high-temperature environments where scaling and corrosion resistance, as well as high temperature strength and good creep resistance are required.Corrosion Resistance The alloy is prone to intergranular corrosion after long term exposure at high temperatures. However, due to its high chromium content (25%), Alloy 310 is more corrosion resistant than most heat resistant alloys.Because of these superb high temperature properties, 310 stainless steel is often used in furnace parts, oil burner parts, carburizing boxes, heat treatment baskets and jigs, heat exchangers and welding filler wire and electrodes.
What does the S stand for in 310S?
CHEMICAL COMPOSITION of Grade 310/s: 310/s Stainless steel contains a higher percentage of chromium and nickel compared to 304. This grade offers superior oxidant resistance at high temperatures. It is suitable for applications involving elevated temperatures, such as furnace parts and heat treatment equipment. In general, 304 is stronger than 303 stainless steel.Grade 310 is an austenitic heat-resisting stainless steel. It is noted for excellent resistance to scaling in continuous service up to 1150°C, and in intermittent heating/cooling conditions up to 1095°C.Most stainless steel ordered around the world is Grade 304. It offers the standard corrosion resistance, formability, strength, and easy maintenance for which stainless is known. While 316 comes in second in terms of quantities sold, it offers vastly superior corrosion resistance to chlorides and acids.
