Gauge refers to the thickness of the metal used to forge or press the utensils. I see some people are confusing gauge with composition which is normally expressed as the ratio of the 2 types of metal added to the steel in the flatware (ie. 1810, 18/10). I have also seen some people incorrectly stating that the nickel is for lustre... that is only 1 function, it is mainly for corrosion resistance and HARDNESS. ANY metal will polish up nicely.
COMPOSITION (aka GRADE):
In order to be called stainless steel, a steel alloy must contain at least 11.5% chromium. 18/10 is the highest quality, it contains 18 percent chromium, and 10 percent nickel.
Chromium makes the metal rust proof and stain resistant, while the nickel provides some additional corrosion resistance and makes the metal hard. The rest is composite steel, which makes the utensils strong. 18/8 stainless steel is normally less expensive and has slightly less corrosion resistance. Really though, it's probably not very noticeable. I have recently seen 18/0 since the world supply of nickel is rather low lately. I would not recommend getting these as they will not hold up well & may even look rather cheap after a few rounds through the dishwasher.
GAUGE:
Gauge is a measure of thickness, generally from 1 to 4 millimeters, and often determines weight and price of the set. Gauge can be compared by looking at pieces of flatware from the side.
Not all utensils in the same set will have the same gauge... the dinner fork should have a thicker gauge and the salad fork a thinner gauge. The butter knife should have a thicker gauge than all of the other utensils. The gauge imparts strength to the utensil, but it also affects the balance & feel of the utensil in your hand. Good flatware should feel balanced in your hand and feel comfortable whether you are cutting, lifting or piercing food. The gauge reflected on the packaging is generally the average gauge of the utensils. Some more unscrupulous companies my label the package with the thickest gauge piece in the package....
Guage is the thickness of the stainless steel, or other kind of metal.
K and V on flatware typically refer to the types of stainless steel used. "K" stands for "Korean Stainless Steel," which is known for its durability and resistance to rust and staining. "V" indicates "Viking Stainless Steel," which is also high-quality but may have different properties or compositions. These designations help consumers identify the quality and type of stainless steel used in the flatware.
No, stainless steel flatware does not contain 925 silver. Stainless steel is a different material composed primarily of steel and chromium, while 925 silver refers to sterling silver which is an alloy containing 92.5% silver and 7.5% other metals.
SSS typically stands for "Stainless Steel Silverware," indicating that the flatware is made from stainless steel, which is resistant to rust and tarnish. PAT-15 refers to a patent number, often indicating a specific design or manufacturing process used in the production of that flatware. Together, these markings suggest that the flatware is durable and has a unique design protected by patent law.
The markings on the back of Oneida stainless flatware typically indicate the brand, the pattern name, and the type of stainless steel used. Common markings include "Oneida," the specific pattern name, and terms like "18/10," which refers to the composition of the stainless steel, containing 18% chromium and 10% nickel for durability and corrosion resistance. These markings help consumers identify the quality and design of the flatware. Additionally, some pieces may have a "stainless" mark, confirming they are made from stainless steel.
How thick thick the metal is.
Oneida sterling flatware had a mark with a "cube" on the left side of the name. According to my reference, it is "The silver cube. Our silversmiths' mark of excellence," and was used since 1965. The cube is apparently a mark of excellence. (American Sterling Silver Flatware, by Maryanne Dolan.)
A number on your flatware typically indicates the thickness or quality of the stainless steel used in its construction. For example, flatware labeled with a number like "18/10" means it contains 18% chromium and 10% nickel, which enhances durability and resistance to rust and corrosion. Higher numbers often suggest better quality and longevity. Additionally, some numbers may refer to the gauge or weight of the metal.
EPSS stands for Electro Plated Stainless Steel. It's a fancy way of saying that Frank Smith flatware is made of stainless steel with a thin layer of silver or other metal electroplated on top. So basically, it's stainless steel with a little bling bling to make it look fancier than it really is.
PAT'06 S on flatware typically indicates that the item was patented in 2006 and the "S" may refer to the style or design of the flatware. This notation helps identify the specific design or manufacturing details associated with that piece. It can also signify that the flatware is made of stainless steel, though this may vary by manufacturer. Always check with the manufacturer's information for precise details.
Stainless Steel
It's simple really... much like Gold 24k is not as hard as 12k. There are different types of stainless steels: when nickel is added, for instance, the austenite structure of iron is stabilized.When considering stainless steel it's much the same as Gold. The lower the gage of metal i.e; 15g verses 18g the better grade of metal. Just because it's a stainless steel sink doesn't mean it will not stain. Often lower price sinks have less nickle and more iron in the stainless. This will allow the sink to develop rust areas and more apt to scratch.
